This summer, Facebook will present a paper at a computer vision conference revealing how it has created a tool almost as accurate as the human brain when it comes to saying whether two photographs show the same person - regardless of changes in lighting and camera angles. A human being will get the answer correct 97.53% of the time; Facebook's new technology scores an impressive 97.25%. "We closely approach human performance," says Yaniv Taigman, a member of its AI team.

Since the ability to recognise faces has long been a benchmark for artificial intelligence, developments such as Facebook's " DeepFace" technology (yes, that's what it called it) raise big questions about the power of today's facial recognition tools and what these mean for the future.

Facebook is not the only tech company interested in facial recognition. A patent published by Apple in March shows how the Cupertino company has investigated the possibility of using facial recognition as a security measure for unlocking its devices - identifying yourself to your iPhone could one day be as easy as snapping a quick selfie.

Google has also invested heavily in the field. Much of Google's interest in facial recognition revolves around the possibilities offered by image search, with the search leviathan hoping to find more intelligent ways to sort through the billions of photos that exist online. Since Google, like Facebook wants to understand its users, it makes perfect sense that the idea of piecing together your life history through public images would be of interest, although users who uploaded images without realising they could be mined in this manner might be less impressed when they end up with social media profiles they never asked for.

Google's deepest dive into facial recognition is its Google Glass headsets. Thanks to the camera built into each device, the headsets would seem to be tailormade for recognising the people around you. That's exactly what third-party developers thought as well, since almost as soon as the technology was announced, apps such as NameTag began springing up. NameTag's idea was simple: that whenever you start a new conversation with a stranger, your Google Glass headset takes a photo of them and then uses this to check the person's online profile. Whether they share your interest in Werner Herzog films, or happen to be a convicted sex offender, nothing will escape your gaze. "With NameTag, your photo shares you," the app's site reads. "Don't be a stranger."

While tools such as NameTag appeared to be the kind of "killer app" that might make Google Glass, in the end Google agreed not to distribute facial recognition apps on the platform, although some have suggested that is no more than a "symbolic" ban that will erode over time. That is to say, Google may prevent users from installing facial recognition apps per se on Glass but it could well be possible to upload images to sites, such as Facebook, that feature facial recognition. Moreover, there is nothing to prevent a rival headset allowing facial recognition apps - and would Google be able to stop itself from following suit?

Not everyone is happy about this. US senator Al Franken has spoken out against apps that use facial recognition to identify strangers, going so far as to publish an open letter to NameTag's creators. "Unlike other biometric identifiers such as iris scans and fingerprints, facial recognition is designed to operate at a distance, without the knowledge or consent of the person being identified," he wrote. "Individuals cannot reasonably prevent themselves from being identified by cameras that could be anywhere - on a lamp post, attached to an unmanned aerial vehicle or, now, integrated into the eyewear of a stranger."

To proponents of facial recognition, of course, this is precisely the point. Like the club doorman who knows you by name and can spot you in a busy crowd, facial recognition can make everything that bit more personal. In Steven Spielberg's 2002 sci-fi film Minority Report, ads are made more personal by using facial recognition technology. As Tom Cruise's character walks down the street, he is bombarded with customised adverts for everything from new cars to alcoholic drinks. In 2014, a number of companies are already bringing these ideas to (digital) life. Late last year, Tesco announced plans to instal video screens at its checkouts around the country. These screens will use inbuilt cameras equipped with facial recognition algorithms to ascertain the age and gender of individual shoppers.

A Californian startup called Emotient meanwhile focuses on the area of facial expression analysis. Incorporated into next-generation TVs by way of a webcam, this technology could potentially be used to monitor viewer engagement levels with whatever entertainment is placed in front of them. The answer to questions such as "how many times did your face register interest during a programme?" can then be fed back to television companies to help them make creative decisions concerning programming.

"It is time for a step-change in advertising," says Lord Sugar's son, Simon, chief executive of Amscreen, which developed the OptimEyes technology behind Tesco's facial recognition screens. "Brands deserve to know not just an estimation of how many eyeballs are viewing their adverts, but who they are, too. Through our Face Detection technology, we want to optimise our advertisers' campaigns, reduce wastage and in turn deliver the type of insight that only online has previously been able to achieve."

Putting aside the question of whether or not brands do "deserve" to know anything and everything about their customers, companies such as OptimEyes and Emotient are far from the creepiest application of facial recognition. In the US, the startup SceneTap (previously known as BarTabbers) has installed cameras in more than 400 bars; they use facial recognition to help bar-hoppers decide which locations to visit on a night out. SceneTap offers real-time information on everything from gender ratios to the average age of patrons. A patent filed by the company even suggests plans to link identified people with their social networking profiles to determine "relationship status, intelligence, education and income".

Although the use of facial recognition tools is still relatively new in the consumer sector, that is where much of the visible innovation will take place over the coming years. "The stakes are lower, so companies are free to take more risks," says Kelly Gates, professor in communication and science studies at UC San Diego and author of Our Biometric Future: Facial Recognition Technology and the Culture of Surveillance. "As a result, there are a lot of experiments in the commercial domain. So what if you identify the wrong person by accident when you're targeting an ad? It's not that big a deal. It happens all the time in other forms of advertising."

There are, naturally, problems, and most relate to privacy concerns. Although privacy is an issue with every form of data mining, at least online the majority of information absorbed by companies is anonymised. Facial recognition, of course, is precisely the opposite. And since facial recognition takes place in public spaces, it is not even necessary for the person surveilled actively to "opt in" to the service.

This, in turns, links to the subject of security, which for many companies and organisations is the ultimate application for facial recognition. Hitherto, most facial recognition research has been funded by governments interested in its potential for streamlining surveillance. That emphasis has only increased over the past decade, provoked by events such as the 9/11 attacks and the 7/7 London bombing in 2005.

One of the most poignant images that came out of 11 September was a grainy frame of surveillance tape footage showing hijacker Mohamed Atta as he passed through an airport metal detector in Portland, Maine. Unlike the horrifying images of the collapse of the Twin Towers, this quieter picture was dramatic because of what it implied: that if only the right technology had been available, that day's tragic could have been averted.

The idea that data mining algorithms have any place in helping us stop the next 9/11 or 7/7 has been criticised in some quarters. But there is no doubt that facial recognition plays an ever more important part in control and surveillance - both in England and overseas. On 5 April 2011, 41-year-old John Gass received a letter from the Massachusetts Registry of Motor Vehicles informing him he should stop driving, effective immediately. A conscientious driver who had not received so much as a traffic violation in years, Gass was baffled. After several frantic phone calls, followed up by a hearing with registry officials, Gass learned his image had been flagged by a facial recognition algorithm, designed to scan through a database of millions of drivers' licences looking for potential criminal false identities. The algorithm had determined that he looked sufficiently like another Massachusetts driver that foul play was likely involved, so he received the automated letter. The RMV was unsympathetic, claiming it was the accused individual's "burden" to clear their name in the event of any mistakes, arguing that the pros of protecting the public outweighed the inconvenience to the wrongly targeted few.

"The dream is for governments to be able to set up networked cameras in public locations, capable of constantly searching through the faces of people who are photographed," says Xiaoou Tang, professor in the department of information engineering at the Chinese University of Hong Kong and one of the world's leading experts in facial recognition. "Once this is done, the images can then be matched to a database looking for suspects or potential terrorists, so that [pre-emptive] arrests can be made."

Perhaps the most notable thing about our faith in facial recognition is what it says regarding belief in the inherent neutrality (or even objectivity) of such systems. "One of the things that troubles me is the idea that machines don't have bias," says Gates. Of course, in a real sense, they might not. Unless a programmer is personally prejudiced and decides deliberately to code that bias into whatever system he or she is working on, it is unlikely that a facial recognition algorithm will exhibit prejudice against certain groups for the reasons that a human might.

But that doesn't mean that prejudice can't occur. It could be, for example, that facial recognition tools show a higher rate of recognition for men than for women and for individuals of non-white origin than for whites. (This has been shown to be true in the past.) A facial recognition system might not target a black male for reasons of overt prejudice in the way that a racist person might, but the fact that it could be more likely to do this than it is to target a white female means that the biased end result is no different.

And while facial recognition algorithms may be neutral themselves, the databases they are tied to are anything but. Whether a database concerns criminal suspects or first-class travellers, they are still designed to sort us into categorisable groups.

"These databases are what define our social mobility and our ability to move through the world," says Gates. "Individual identification is always tied to social classification. It's always there for some specific purpose, and that's usually to determine someone's level of access or privilege. The ethical questions in facial recognition relate to those social hierarchies and how they're established."

"I think it worries people because there's something very permanent about it," says Xiaoou Tang. "Even when you're talking about using your face or your fingerprints to unlock a phone, this is a password we can never change. We only have one, and once it's set up it's going to be your password for life."

This isn't to suggest that facial recognition doesn't have its positives. As computer vision continues to get better over the coming months and years, we'll reap the benefits as computer users. The idea that we can take the giant, anonymous world we live in and transform it into a place as knowable as a small town is, at root, a utopian/naive one. "Ultimately we need to ask ourselves whether a world of ubiquitous automated identification is really one that we want to build," says Gates.

It's important to understand the scale of change that is under way, because it is going to dictate what happens. Knowing about facial recognition, and how it is used by both governments and companies, is key to helping us face the future. No pun intended.

If you're after a mega bargain, but don't want to use a feature phone or a modern, mid-range handset, the Galaxy S5, while old, is now available for under $200.

That's right: you can pick up a reconditioned Galaxy S5 via Gazelle for around $158-$168. Ideal if you're operating on a budget.

As I said, the Galaxy S5 is a little long in the tooth these days but with a decent custom ROM installed on it, you should get very competitive performance. A custom ROM is a must as well; I use CyanogenMod.

With a custom rom installed, you can run the handset without any bloatware and protect yourself from Samsung updates which often cripple older handsets.

As I said: this handset isn't new, but for the price it still offers up plenty of value. Even more so if you install a custom ROM on it.

Also: it has a removable battery, meaning you will get potentially years of use from it as you can simply swap out a dead battery for a fresh one once its run its lifecycle.

You cannot do this anymore; all Android handsets now feature secured battery cells. So when that cell dies, so too does your phone, forcing you to upgrade.

-------------------------------------------------------------------

Samsung's Galaxy S flagship smartphone line is easily the best known and most prominent device series outside of Apple's iPhone stable, and certainly one of the best known Android brands. Over the years the Galaxy S flagship models have sold like proverbial freshly baked delicacies, winning plenty of fans over in the process. So it's not surprising at all that ahead of the Galaxy S5's launch in early 2014 there was a more than a little hype around the handset's imminent arrival and what features it might be carrying.

A major source of the excitement was the torrent of rumours and leaks coming, as it typically does these days, from sources inside Asian manufacturing, retail, and supply - the bulk of the information pointed to a substantial design overhaul, and in particular focused on Samsung using new and interesting build materials (for Samsung), such as metal and carbon fibre.

Sadly, this has turned out not to be the case, and the Galaxy S5 is made from plastic just like its predecessors. Consequently there's been an air of disappointment hanging over Galaxy S5 reviews and feedback circulating on the web.

Samsung's sales might not have been great in 2014 compared to previous years, but consumers' perception of the company appears to have sky-rocketed, as noted by a recent poll by research firm Harris. "Samsung surpassed Apple for the first time in its annual Reputation Quotient study on the 100 'most visible companies' in the United States," reports Phone Arena. "The research spans across six main categories, including social responsibility, emotional appeal, products & services, vision & leadership, financial performance, and workplace environment. Samsung bested Apple in three out of these six."

Is the Galaxy S5 as bad as they say, though? The phone still has a plenty capable processor and buckets of good hardware onboard. We took one for a spin to see if it's a worthy successor model... or whether you're better off with a Galaxy Note 4 or, waiting a smidge longer, and getting the Samsung Galaxy S6.

Samsung Galaxy S5 Review: Design & Build

Physical build and style are some of the areas where many were anticipating the biggest changes for the handset, but sadly the rumours and hype proved untrue. The Galaxy S5 is not particularly far removed from its predecessor design wise. Consumers en masse picked up on this, as did critics, and Samsung reacted by completely relocating its entire Galaxy S5 design team. No one was fired, however, but the team behind 2015's Galaxy S6 is likely to be completely different to the one that gave us the Galaxy S3, Galaxy S4 and Galaxy S5.

The overall shape is virtually identical to the Galaxy S4, but the Galaxy S5 handset is a bit larger to accommodate an expanded display and a bigger battery cell. Proportions wise, it's also a similar story with a relatively narrow bezel, but nothing extreme. The silver surround is similar to the Galaxy Note 3's with ridges to aid grip.

While we don't exactly do stress testing at Know Your Mobile, by this point there's little reason to doubt Samsung's Galaxy S5 is relatively durable - Samsung has established that it knows how to make a phone which can take a few knocks. However, anyone hoping for a more premium-feel finish is going to be left sorely disappointed. If anything, Samsung has taken some steps back here - I'm a fan of matte finish plastics over glossy ones, so you'd think I'd be the first to sing Samsung's praises for ditching its old shiny ways.

But, what we have in exchange is something as bad, if not worse. The silver surround and other components are still glossy plastic but the back panel is this weird matte plastic with a very odd feel to it. It has a slight softness while still being solid and almost feels like some kind of hardened polystyrene, which is not great to touch and looks cheap and tacky. On top of that you have this ugly dimpled texture across the entire panel, making the phone look like it's been clad in some kind of grotesque synthetic chicken skin.

It doesn't concern me that the Galaxy S5's build is not metal as per earlier rumours, indeed, I'm really not too bothered what it's made out of. But the point is if you're going to go with plastic (or any other material) you can either have stuff which feels nice or stuff which feels gross. Quite simply, Samsung has changed which type of gross it has chosen. I realise beauty is in the eye of the beholder and all that, but personally I think Samsung has now got a firm track record of having pretty poor taste in material finishes - its designers just do not know what feels or looks good, or rather, what they think feels and looks good is entirely unattractive to me. So far I'm yet to encounter anyone else who actually likes the Galaxy S5's back panel material, even amongst fans of the Galaxy S4 or earlier iterations.

I'll also add that although KYM's review unit was a white model, I've seen the gold version in the flesh and it's pretty damn hideous, being a particularly bling-bling implementation of the metallic tone, rather than some of the more tastefully subdued stuff we've seen from the likes of HTC and Apple, to name but a few.

While the phone has become slightly larger than its predecessor it's by no means difficult to handle and operate, being a comfortable size in the hand. It's nice and lightweight, while also being fairly well balanced. One-handed use did not pose a problem for me, although those with smaller paws may find things a bit trickier.

Samsung has also added to the phone's durability with an IP67 water and dust resistance certification. This is supposed to handle being submersed in up to a metre of water for up to 30 minutes, however, some tests on the web have showed it to endure an hour or more.

This also means the microUSB port at the base of the device now sports a flappy port cover for the microUSB/MHL port similar to those found on Sony's Xperia Z2 - while the flappy cover didn't come off during my time with the device, as with Sony's implementation, it doesn't exactly inspire confidence for long-term durability.

Despite this change, many may be pleased to hear that the Galaxy S5 retains a removable back panel and removable battery cell, along with internal slots for the microSD and Micro-SIM cards.

I put the Galaxy S5 under a running tap and it coped very well indeed, though I should note the pressure of the water actually activated the touchscreen.

Other physical features remain very similar to Samsung's previous models; the power key is towards the top of the right-hand side and the volume rocker at the top left. The headphone jack is at the top, microUSB at the bottom, and just beneath the screen is a large physical Home key flanked by two capacitive controls which only light up during use - multitasking is on the left and "Back" is on the right.

Overall the Galaxy S5's exterior is fairly mundane looking and uninspiring to handle, but it does have good durability features.

Not Loving The Design? Want Metal? Consider The Samsung Galaxy Alpha

If you're one of the people who was disappointed at the lack of metal on Samsung's Galaxy S5 flagship, there may be an alternative option for you: the Samsung Galaxy Alpha.

Sure, it might not pack all of the same perks as Sammy's higher-end blower, things like waterproofing and Snapdragon 801 processors, but as KYM's Editor Richard Goodwin discovered in his full review of the device, it still has a lot going for it. Crucially, it has a metal surround, which goes a long way to make the Alpha feel miles more premium than its flagship counterpart. The processor may be lower spec, but it's well optimised with Android 4.4 KitKat and is more than capable of running Google Play's high-end content smoothly. Meanwhile, the camera and display are also rewarding.
Check out the Galaxy Alpha review here.
And if that still doesn't do it for you, we've heard reports that Samsung is working on an all-metal phone called the SM-A500. You can read about that here.

Samsung Galaxy S5 Review: Display

I've come to expect good things from Samsung's display division and the Galaxy S5 doesn't fail to deliver. The display is a wee bit larger than its predecessor measuring 5.1-inches on the diagonal. It has a full HD 1080p resolution giving a pixel density of 432 pixels-per-inch (ppi). Some may have been expecting a QHD setup and could be disappointed at the lower resolution, but I actually think Samsung's choice here is a good one.

The 1080p resolution still looks fantastic in terms of image clarity while being friendlier to the battery. Colour is vibrant and brightness is excellent; it handles use in direct sunlight quite well and viewing angles are seriously wide.

Text is nice and sharp, whites have plenty of pop and, being a Super AMOLED, contrast is robust with deep blacks and dark tones. In my opinion this screen is a good deal better than the HTC One M8's and is easily one of the best flagship displays on the current market.

Samsung Galaxy S5 Review: Processor

The Galaxy S5 was a little too early to the party to get a next-gen Qualcomm Snapdragon 805 chip, but instead gets a decent enough upgrade from the original Galaxy S4 (if you don't count the Snapdragon 800-equipped Galaxy S4 variant, that is) with a Snapdragon 801.

This chip (the MSM8974AC) is a quad-core model using four Krait 400 cores clocked at 2.5GHz, with an Adreno 330 GPU. The GPU and onboard memory are both clocked faster at 578MHz and 933 MHz (14.9GB/s) respectively, compared to the older Snapdragon 800's 450MHz and 800MHz (12.8 GB/s) with a lower chip clockspeed of 2.3GHz. Needless to say it's a good deal quicker than the Snapdragon 600 aboard the original Galaxy S4 launch model too.

Number crunching aside, the important thing is that the Galaxy S5 offers excellent performance as we've come to expect from this chip. It's easily on a par with similarly equipped rivals such as the Sony Xperia Z2 and HTC One M8. Interface operation, browsing, multimedia and gaming all function smoothly and with no lag to speak of.

Samsung Galaxy S5 Review: Software & UI

Android 4.4 KitKat might not be a massive leap forward for Google from the previous build, but Samsung has implemented the software impressively in the Galaxy S5. Partly this is due to the new TouchWiz UI design embracing Google's "flat" design ethos more than ever before. But another key element is that Samsung has added some interesting Google Now and voice control features previously seen on Google's Nexus devices. There's also a selection of new health related features, but more on that later.

But first, that UI.

I've always thought TouchWiz was a bit too garish and busy, but with the latest iteration it seems Samsung has decided to keep things in-line with Google's vision for a clean and simple OS.

For starters, as per pretty much every other flagship Android handset running KitKat, the heavy black box design has gone in favour of transparent UI elements - most notably the app drawer, notifications bar at the top and navigation/apps bar at the bottom.

As with previous Samsung UI builds, the drop-down notifications centre and Quick Settings menus are quite different from stock Android, however, once again Samsung has simplified and flattened these menus more than before and has kept its bright green highlight colour.

The drop down menu features a scrollable bar of quick setting toggles, a brightness bar and auto brightness toggle, and shortcuts to both a full panel of quick setting keys and the full Settings menu. You can also customise what controls appear in the notification panel.

The full Settings menu is one area where Samsung's flatter approach is most visible - all of the icons are plain coloured discs with white icons in the middle. Current Samsung Galaxy users may at first be a bit surprised to find the tabbed settings menu has gone, but this is actually just the default setting on the device - once again, Samsung has embraced customisation options here and you can choose from a number of different layouts for your Settings page, including the old tabbed style.

Samsung's app shortcuts also seem less jazzy than they used to be and are all the better for it. Generally the UI is nice and simple, which is a massive plus point for Samsung as this isn't where TouchWiz started. You can also customise the fonts and homescreen transition effects.

Samsung's Multiscreen feature makes a welcome return and appears much the same as it was before; you can select two apps from an extensive list of compatible ones and divide the screen between them. It's handy for checking emails and web browsing at the same time and adds an additional layer of multitasking on top of Android's standard carousel.

Another thing worth noting is the phone comes with a "My Magazine" page enabled by default - this is effectively an HTC Blinkfeed style setup which aggregates Flipboard feeds and social networking. You choose what goes here by picking sources, and if it's not to your taste you can disable it entirely. Win. Win.

In terms of other useful apps Samsung has bundled onboard you've got DropBox, a "Memo" app for note taking, and a dedicated "My Files" file browser. This last one is particularly cool with a nice, simple UI and quick filtering categories for things like recent files, downloads, or specific multimedia types (audio, images, documents, video). You can also access your entire file directory under Device Storage and Dropbox direct from this screen. Handy.

S Health

Then there's S Health. For some users this is going to be a gimmick, while for others it could well be the most-used app aboard the handset, it really depends on whether you're into your fitness or not...obviously. Well, that's not entirely true, the app does also have some stuff for stress management and sleep habits via the "Coach" section which could be beneficial to anyone. But apart from this it's all about the exercise, weight, heart rate and food - ie: getting in shape.

The S Health app allows access to the handset's onboard pedometer and lets you monitor your heart rate through the fingerprint sensor, which sits next to the camera flash on the rear panel. These components aren't just in isolation though; the app prompts you to set up a profile which will allow you to track health over time. You can also set yourself goals and unlock achievements, such as a specific weight or a number of steps per day.

You're also able to view statistics, charts and logs collating this data. It's possible to put exercise and training regimes in place, including audio prompts, location-based training and music playlists for running, walking, cycling and hiking. You can track your food consumption and calories per day, including pictures. Naturally a whole heap of this information is shareable via a range of avenues, including social networking, all from within the app.

On top of all this, S Health has been designed specifically to pair with Samsung's wearable range - the Gear 2 and Gear Fit are both able to offer more accurate heart rate and pedometer readings which can be synced to the phone. You can also get notifications through the smartwatch devices.

In short, Samsung has produced a really very comprehensive health and fitness suite which is well worth a look if you're into that sort of thing. I'd hesitate to say it's the best, as some dedicated standalone apps appear to go into more detail, but even so it's up there as one of the better options and is built right into the phone.

Samsung Galaxy S5 Review: Hardware, Storage & Connectivity

The Samsung Galaxy S5 comes in either 16GB or 32GB internal storage variants with microSD support for cards up to 128GB. Some power users might hanker after a 64GB model but aside from this I reckon the needs of most people are probably well covered here.

Another hardware feature is the fingerprint scanner embedded in the Home key. You can register up to three fingerprints (which could feasibly be between different people if you like), but notably Samsung's tech recognises the differences between, say, two index fingers on the same person (unlike the HTC One Max), so you could instead register multiple digits from yourself to make things easier. The scanner pretty much only has two functions though: paying for stuff with PayPal and unlocking the phone.

As it requires a specific, gentle swiping gesture rather than a hold press (which quite often doesn't register properly) there seems little point to this latter function when a pattern, PIN, or password lock will serve just as well and seems like it takes a similar amount of time (or less) to input. Basically, the scanner's unreliability is its undoing, it's far less frustrating to go down the conventional route.

As usual for a flagship, connectivity includes 4G LTE, Bluetooth, microUSB and dual-band Wi-Fi, as well as DLNA, Wi-Fi Direct, Wi-Fi Hotspot, NFC, infrared, GPS and MHL TV-Out.

There's also a specialised Download Booster mode which uses both Wi-Fi connectivity and your mobile data to increase download speeds. This makes a noticeable difference when using 4G but using a 3G SIM it didn't seem much quicker than just Wi-Fi alone. Of course, this will still eat your data allowance so should be used sparingly unless you have an unlimited data plan.

Samsung hasn't opted for a particularly fancy speaker setup. It's a single rear-facing speaker which delivers quite loud volume with little in the way of distortion, but it lacks the punch we've seen on other high-end models as well as the obvious lack of any stereo capability for a better listening experience. Sound quality can be a little tinny in places and you can pretty much forget about a decent range for treble and bass. Still, this is far from the worst speaker setup I've seen and it is adequate, just not thrilling compared to recent offerings from the likes of Sony and HTC.

Samsung Galaxy S5 Review: Battery

The removable battery pack is rated at 2,800mAh, just shy of that 3,000mAh we're used to seeing on many flagship models these days. With light-to-moderate use I found this typically lasted me a couple of days on a single charge with data and Wi-Fi on, and full brightness.

In our video test from 100% charge running Django Unchained for 2.45 hours (with full brightness, Wi-Fi and mobile data on) the Galaxy S5 finished with 61% charge remaining. This is not too shabby at all and should mean you can get more than five and a half hours of continuous video playback. Gaming is more intensive, as usual, and will really eat into the battery much quicker.

Ultra Power Saving Mode

The Galaxy S5 also has an Ultra Power Saving mode which can be toggled via the quick settings menu. Toggling this on or off takes about 10 seconds or so, but when it's activated you're presented with a simplified homescreen in black and white. The homescreen features six app slots - by default you have Phone, Messages and Internet - while the remaining three show plus icons allowing you to add more apps from a limited selection. You can also replace the pre-selected apps if you wish.

The screen also presents you with the battery percentage and an estimated standby time in days. On maximum charge this is around 12 days, but as you can see from the photo below at 37% it will still last 4.6 days, while at 50% it said 6.2 days. At 10% or less you're still looking at a couple of days in this mode.

As a feature this is basically essential, and it's weird we haven't seen something similar added to a smartphone before. You can still call and text - and even use data if you wish - but your phone's battery life will be extended dramatically. Case in point: from 4% I was told my S5 would last another 21 hours once Ultra Power Saver was activated. That is beyond impressive and, if your phone has ever left you high and dry before, it's a real blessing to know you have something like this at your disposal.

In my time with the device I found these predicted lifespans were pretty accurate if you use the phone in the way this mode intends - primarily for calls and texts. The app choices allow you to use Facebook, Google+ or the web browser, which are nice to have for limited use, but both will use mobile data and eat into your battery at a fairly normal consumption rate.

Essentially, if you do use this mode, use these other apps very sparingly or you'll nullify the usefulness of Ultra Power Saving altogether.

Samsung Galaxy S5 Review: Camera

With a number of Samsung's recent smartphones I've been rather enamoured with the imaging capabilities. With devices such as the Galaxy S4 and Galaxy Note 3, Samsung hit a good balance point between visual quality and ease-of-use, and I found that consistently, Samsung offered a very rewarding experience in terms of easy "point and shoot" operation with excellent picture results.

The Galaxy S5 debuts Samsung's own ISOCELL sensor technology, featuring a larger 1.2.5" sensor than the Galaxy S4/Note 3's 1/3.06" setup, meanwhile the aperture remains Samsung's rather balanced choice of f/2.2. The ISOCELL sensor is rated at 16-megapixels, up from the 13-megapixel rating on the aforementioned models. It features an LED flash and video recording from 720p up to 1080p and 2160p (4K).

Many other camera specs and features are things we've seen repeated on several Galaxy models: dualcapture (front and back cameras at the same time - including video and video calls), HDR (now with live preview), simultaneous video and still capture, digital stabilisation, auto focus, touch focus, face and smile detection, burst mode, tap to capture, a range of filters, timer, geo-tagging, panoramic capture, beauty face, and voice control.

"Shot & more" also lets you capture a series of images and pick Best Photo, Best Face, "Drama Shot" (time laps motion capture), Eraser (remove unwanted elements from a shot) and Panning Shot.

A prominent new addition is "Selective Focus". This has been described as being rather like a Lytro camera or the HTC One M8's "U Focus" in that it allows you to re-select the focal point of an image after capture. However, it functions a little differently here. For one thing, you need to select the specific Selective Focus mode in order for it to become active (where on the HTC One M8 it's an option for most captured shots).

For another, as you'll see when the mode is selected, it requires some very specific circumstances to function properly - a message will appear saying you can "Make objects stand out from the background," but that "They must be less than 50cm away from you, and at least three times this distance from the background". Upon capturing said object the phone will go through a quick processing procedure much as you'll commonly see with HDR modes or similar.

The phone effectively captures the foreground and background data in one go and then separates them out. This information is stored in the image file, so whenever you bring it up on the phone you have the option of editing the focus between foreground (Near focus), background (Far focus) or both (Pan focus).

Oddly enough I found this more effective than HTC's fancier U Focus on the One M8 (which uses a dedicated depth sensor above the camera lens), which in practice simply served to blur out anything but the selected area. It's much easier with the Galaxy S5 to get a usable image from this arrangement. HTC's offering did do better in one regard though: you were able to save your edited images as separate files, where the Samsung Galaxy S5 simply overwrites the existing image - it keeps the stored data, however, so you can still re-select the focus as much as you like.

Samsung's camera UI is great, it's nice and simple with clear icons, and menu controls which are easy to find and use. It's also unobtrusive, with much of the screen giving way to the viewfinder and many controls being semi-transparent overlays on top of this.

The picture quality is excellent - a noticeable improvement on its predecessor and plenty capable for a current flagship. Detail is nice and crisp and there's no noticeable noise or fuzz to complain about. Colour reproduction is also nice and natural, and both contrast and dynamic range are robust - generally I'd say the images captured were fairly accurate to how things looked to the eye at the time.

The handset performed quite well in low-light conditions, although with the flash on it was somewhat overzealous it did still manage to capture plenty of detail.

All of this comes once again without much fuss. It's a rewardingly simple affair to capture fantastic images on the Galaxy S5 - just aim at what you're after, tap to focus if needs be, and hit the capture button. It must be said it's not always so care-free on rival devices.

Samsung Galaxy S5 Review: Conclusion

The Galaxy S5 is most definitely a mixed bag. On the one hand, the disgruntlement regarding the exterior design is entirely understandable; not only is it not the advancement many expected, it's actually a bit of a step back with that revolting back cover.

Samsung Galaxy S5 User Guides

Now that you're a happy Samsung Galaxy S5 owner, you're probably wondering about some of the more esoteric features and abilities locked inside your shiny new Android phone. Well, as it happens, we've put together a veritable cookbook of usual user guides and tips and tricks articles designed to help you get the most out of your Galaxy S5. Check 'em out below:

But when you boil it all down that's one of only a small number of bad things I have to say about it. On the whole this is actually a pretty great smartphone. It's fast and powerful with stacks of storage space and connectivity options, and the screen is gorgeous. The waterproofing is a real boon too, as you don't have to worry about Tweeting from your bathtub.

I think a big improvement for Samsung which hasn't been mentioned much elsewhere is that the TouchWiz interface has really matured into something rather special - it's very much more in keeping with Google's modern Android ideal, being simpler and more understated, but with plenty of user customisation options. It may have taken a scolding from Google for this to happen, if rumours are true, but it's still a step forward nonetheless.

Samsung's camera offerings continue to go from strength-to-strength. It may not be the best on the market in image quality alongside such titans as the Xperia Z2 and Lumia 1020, but it definitely holds its own in this regard all the same, as the image quality is still certainly more than adequate (excellent, in fact), but also offers one of the most effortlessly usable configurations I've seen to date.

Then there's the battery. The phone's normal battery life is easily on a par with similar flagship rivals such as the HTC One M8 and Sony Xperia Z2, while also sitting in a similar position to the impressive Galaxy Note 3. However, Samsung's Ultra Power Saving mode is one of the better battery saving modes I've seen so far and really does extend the phone's lifespan significantly when you need to keep it alive. The Galaxy S5 also has the admirable trait of a removable battery cell, meaning you can carry spares or replace a faulty unit.

The S Health features are very much "take it or leave it" but if you do take it you will likely find it a rewarding experience. The speaker is a bit of a disappointment and the fingerprint scanner is pretty much a waste of time as far as I'm concerned. I don't see the point of it, but if you do have one at least make it work reliably and easily - the Galaxy S5's falls on both counts.

As with previous Galaxy S flagships, case makers will likely produce plenty of replacement back panels for the Galaxy S5 in every material, finish and colour you can possibly imagine, so the Galaxy S5's squiffy design ideas should be relatively easy to overcome. Apart from that, it's one top-notch smartphone in more or less every other regard.
