Reviews Paul Briden 17:55, 18 Sep 2014

Should you consider the LG G3 as your next smartphone? We road-tests it to see what's what

Typical Price: 
Attractive design, Great performance, Excellent display, Brilliant camera, Great UI
Knock On can cause issues with unwanted screen activation, Gets hot, Some scenarios tax the battery
A really excellent high-end Android smartphone with one of the best displays currently available and a rewarding user experience

It seems as though the smartphone market is moving faster than ever, but at the same time every new handset appears to make a few tweaks here and there - the massive leaps and bounds are a thing of the past, clones are common, and a feeling of over-familiarity has set in. Understandably in this environment, technical innovation is more important than ever beofre, because it means the difference between a new phone getting noticed or being largely ignored. Manufacturers need to ensure they distinguish their handsets from the plethora of large-screened, high-res, souped-up monster slabs, which all sport a near identical look and feel. It's a walk on a knife edge though,  as attempts to differentiate are fraught with risk – throwing in some clever new functionality has the potential to turn around and bite you in the ass if it turns out to be awkward, inconvenient, or just plain uninspiring. Such things are difficult to predict too.

The LG G3 follows on from LG's impressive LG G2 flagship, and it has more than a handful of showy tricks up its sleeves. Do they benefit the experience or is the phone all mouth and no trousers?

Design & Display

At a glance the LG G3 is an attractive beast with some qualities not seen elsewhere on the smartphone market. Primarily, it’s all about that massive touchscreen, being one of very few offerings available which could genuinely be described as “edge-to-edge”. I can’t even begin to put together the mathematics to prove it as fact, (because writing for a living means that maths is basically wizardry) but to me it feels as though bezel width is directly proportional to phone attractiveness, ie: the narrower it is the better looking the phone becomes.

But the really curious thing seems to be how much LG appears to have been listening in on consumers’ wants and desires, vis-a-vis what everyone was saying prior to, during, and after the launches of the Samsung Galaxy S5 and HTC One M8.

That’s really the only conclusion I can reach when what we have here is a phone which goes to great lengths to make itself look like metal, but is in fact plastic, though not the kind of crap-feeling plastic which seems like it’s been reconstituted from all the unwanted drinks straws thrown away by fast-food chains.

Yes, LG earns some major cool points on the build front. The shape of the device looks different enough from most rivals with an overall angular profile. I suppose the nearest look-alike would be the LG-made Nexus 5, although the back panel has a more pronounced curvature on the G3. It’s also not using any of that soft-touch plastic, this is solid stuff with a smooth, though not overly glossy finish and a brushed metal-effect texture.

As I’ve come to expect from the last few LG flagships, the build quality is solid and it’s quite a robust device. However, while it’s likely more durable than aluminium, and it did survive a few heavy drops, I have noticed a bit of scuffing to the plastic finish in one of the corners.

The LG G3 handles reasonably well on the whole but it’s worth pointing out the tapered edges don’t give the best grip, combined with the size and the fact that, while not glossy, the material finish is quite smooth and slippery, those with smaller hands may struggle to hold onto the device.

While it may look like a unibody device, the back panel is in fact removable, revealing a removable 3,000mAh battery and card slots inside. Meanwhile, LG has pulled the same trick it performed on the LG G2 in streamlining the phone’s exterior and isolating the controls to the top centre of the back panel, just below the camera port.

This comprises a central power button housed in the middle of a volume rocker, just as before, although it’s been made to look a bit flashier than the LG G2 in-line with the rest of the phone’s metallic theme. The power key has a brushed effect and the volume rocker has a small dimpled texture, both of which are physical rather than simply visual and therefore make the keys a bit easier to locate on the back of the handset. I maintain it’s still not as easy to operate as a regular side or top-mounted power key and volume rocker, however, and for some reason on our review unit the power key had a tendency to stick or jam slightly. I've also found over time the power button can behave oddly, powering on the handset only to shut the screen off again immediately - as many as three or four times in a row before it actually decides to play nice and keep the screen on.

What about the display? Well, it’s pretty stunning really. It is incredibly sharp, thanks to LG further refining its use of IPS+ LCD with a denser sub-pixel arrangement and an insanely high-resolution at 2560x1440 pixels QHD. At 5.5-inches on the diagonal that gives a pixel density of 534 pixels-per-inch, meaning there’s little else on the market that comes close in terms of clarity. Colour is also nice and vivid, whites are very pure and there doesn’t appear to be any tint throwing off the whole setup.

Blacks and dark tones have good depth, although are not the deepest compared to something like an OLED setup, but brightness is excellent in general use. Viewing angles aren't too bad either, and it’s a similar story for bright sunlight, with the G3 besting most of its high-end Android stable mates. Generally speaking though, it’s a film or game lover’s dream in terms of usability as your own little portable cinema screen – viewing multimedia is a joy.

Is The LG G3 Waterproof?

You may have noticed a recent trend in the smartphone space towards waterproofing handsets with "IP" durability certifications. In terms of high-end, mainstream handsets this was pretty much started by Sony with its IP58 certification aboard the Xperia Z series, but other phone makers have followed suit, with Samsung sticking IP67 certification to the Galaxy S5.

With the launch of the LG G3, LG made no mention of any such  protection from the wet stuff for its latest flagship. For now, officially at least, it seems it doesn't have it.

Unofficially, however, some users have been bravely putting it to the test agains the elements and have found it to be surprisingly robust.

Youtube user and LG G3 owner Harris Craycraft took to the video sharing site to show how his handset survived two whole hours underwater.

He left the display turned on during the procedure and afterwards it still appears to function normally.

As PhoneArena points out, the video does not show whether delicate components such as the microUSB port, audio jack, or speakers, are either damaged or still effective. In waterproofed devices these areas are either treated with a water resistant coating or covered with ports, or in the case of the speakers, surrounded by an internal rubber seal. Popping the back off our LG G3 it certainly seems there's no seal around the speaker and we know there's no port cover on the USB as there is on Sony and Samsung's hardware.

We've been in touch with LG for a statement on the G3's water resistance capabilities, but in the meantime, while the experiment is certainly interesting, we'd still advise users to avoid getting their handsets wet for now. We will, of course, update further as we hear more.

Software & User Experience

The LG G3 uses Google’s Android software, version 4.4 KitKat, which until the recently unveiled Android L rolls out, is the most up-to-date build. It has LG’s own custom UI layer on top, which presents an interesting, if somewhat idiosyncratic, set of features – some of which are tied into hardware functionality.

One of these is the return of the Knock On feature seen on the LG G2, which allows the user to wake or sleep the phone by double-tapping on the display. This is now joined by Knock Code, but I’ll come back to that in a second.

Now, previously I made a rather glib comment during our LG G2 video that Knock On was “gimmicky”, which I’ve since come to regret as it actually does have it uses and is not a bad little feature. It’s not without its problems, however. Firstly, LG suggests it operates via a double-tap, but in practice I've found it only really responds consistently to a triple-tap.  Secondly, it's a bit overly sensitive – enough so that I quite often found the phone would wake up in my pocket. That led to one of two scenarios, either I’d take the phone out to use for something else, only to find it already on, and perhaps pratting about inside an app (I haven’t sent so many nonsensical “zzzjsdhdhdhd” style text messages by accident since the early 2000’s).

It also gets pretty hot too.

And that should give you an ominous indication of the next scenario: last week I noticed something burning a frigging hole in my chest. Alarmed, I investigated only to discover it was the phone. Screw wearables, this thing will bring about a glorious cyborg union much earlier, whether you want it to or not, when it fuses itself to your ribcage or hip.

Less dramatically: think of the battery drain.

I’ve encountered this before, with a similar feature aboard the HTC One M8, but the key difference there is that HTC lets you toggle it on or off. I’ll concede I may have missed it, but I looked long and hard through the LG G3’s UI and found no such toggle – you can’t switch off Knock On, it seems.

Which means the only real way to stop such tomfoolery is to activate Knock Code or some other security lock instead. Knock Code acts as another unlock option alongside the usual run of PIN, password or pattern unlocking. It’s similar to pattern unlock, except that it lets you set a knocking pattern for tapping the screen in order to unlock it (rather than a swiping pattern), using specific sections of the display. It’s a bit like having a secret knock, and it works very well.

This can be a remedy to the aforementioned overactive-in-your-pocket scenario caused by regular Knock On, simply because the odds of it hitting the right code while jumbling about in your pocket are pretty damn slim – it might still activate the display, as that still works on a double tap, but your code isn’t likely to be entered, which means you won’t get into apps, tax the processor, drain the battery, or start sending derpy messages. And even if it is activated in this case, if you don’t input your code it will time out from the lockscreen.

Remember what I said about getting bitten in the ass? Yeah, that was it. I understand the good intentions behind this feature, but from a practical standpoint it falls flat on its face.

What about the rest of the UI design? Well, as seems to be the trend of late, Android 4.4 KitKat has seen a lot of phone makers which have conventionally slapped a thick layer of brand flavour icing onto things opting instead for something a bit more reserved and, dare I say it, “true to Google”.

The LG G3’s UI is very much in-keeping with KitKat – it has flatter app icons, white notification elements, transparent bars at top and bottom, a translucent app drawer and plenty more along these lines. The Quick Settings section of the drop-down notifications menu is particularly noteworthy for its neat little circular toggle icons. Meanwhile, there’s customisation a-plenty with the ability to change the Quick Setting toggles, adjust the full Settings menu viewing mode (tabs or list), and select a custom font.

The keyboard has its own bag of tricks, as well as offering a Swype-like text input you can customise the height of the keyboard – either condensing it down or spreading the keys out a bit. You can also toggle one-handed operation where you can flip the keyboard to one side of the handset or the other with a swipe, which is nice.

A neat feature is the “Dual Window” functionality accessible via the multitasking screen. Rather like Samsung’s Multiscreen, you can share the display between two apps – you can even set this up so that links and image attachments will automatically open in the Dual Window mode. The handset also features a built-in File Manager application, QuickMemo+, and a configurable “Guest Mode” to give restricted access to whoever you might hand your phone to.

One little quirk is the “Smart Bulletin”, which is rather similar to some of Samsung’s stuff and HTC’s BlinkFeed as a panel positioned on the far-left of your set of homescreens. It comprises two panes, one for the LG Health suite (which is pretty much like all the other helath suites being pushed right now) and one for “Smart Tips”, which can guide you in how to use certain features aboard the phone. The whole Smart Bulletin feature can be handily toggled off in Settings should you wish to be rid of it.

Performance wise this is as buttery smooth as I’ve come to expect having handled the LG G2 last year, and subsequently a boatload of Qualcomm Snapdragon 801-based handsets. It’s crazy fast and doesn’t skip a beat. But importantly the UI operation appears to have been well optimised. There are a lot of similarities in look, feel, and animation style and fluidity, with HTC’s Sense 6 UI, which is a very positive thing as I wrote enthusiastically about that in my HTC One M8 review. It’s rewarding to operate and view, and it’s fluid too.

Android L?

Back at Google I/O 2014 the Android maker unveiled the latest version of its software, dubbed Android L. LG has said nothing on the subject of updating its current flagship to the new software when it is officially released, but being the company's current high-end device it's extremely likely that it will. Current rumours suggest Android L will carry a 5.0 version number following KitKat's 4.4. It's also been hinted that it may be called either "Lollipop", but the most recent murmurings claim "Lemon Meringue Pie". Interestingly, leaked details imply Android L will be rolled out officially in October, together with the launch of new Google Nexus devices.

So what can we expect to see if/when the new update lands on the LG G3? That's quite tricky to say, not in the sesne that we don't know what's coming, but more that Android L's big changes affect the look and feel of the platform and its apps due to the new "Material Design" approach. Naturally, with interface overlays such as LG's on top this may go largely unnoticed, or it may be a key feature - it depends how the manufacturer chooses to implement things.

Assuming LG does embrace Material Design though (which it is likely being encouraged to do by Google), you'll see a flatter interface design and plenty of cues inspired by Google Now's card-based visuals. On stock Android L, for example, notifications have been completely overhauled and are now very much like Google Now cards wherever they appear (and that includes the lock screen).

A key pillar of Material Design is in making interface elements intuitive. Google's design lead, Matias Duarte, said the interface was inspired by the physical properties of real world objects, like paper, where because of the way they look in their environment (shadows, highlights, texture etc.), people intuitively know how they can interact with them and how they will move or react.

A lot of this revolves around giving developers (such as LG - the UI being just a software skin, after all) a set of tools to work with that will help make the look and feel cohesive with Google's vision. Google's SDK includes animation and transition templates, as well as the ability to set the depth of UI components. Android L features real-time dynamic lighting sources to provide uniform shading and highlights across UI elements, should a developer wish to use them. Google's native apps will be getting this visual overhaul rolled out, and the big G is also adding a new "People" app for your contacts.

Other enhancements include "Project Volta" to help monitor and optimise power consumption and charging times - it'll also include a native Power Saving Mode. Another new feature is "Personal Unlocking", where if you use a security lock for accessing the phone, you can set certain "safe" circumstances where it won't be needed, for example, if you're at home (GPS will tell the phone this is the case) or if you're wearing a paired smartwatch.

Connectivity &  Hardware

All the connectivity options you might expect from a high-end smartphone are aboard the LG G3, including full 4G LTE and 3G mobile data (via a Micro-SIM), dual-band Wi-Fi (with Wi-Fi Direct and Hotspot), Bluetooth 4.0 and microUSB. It also packs DLNA, an infrared blaster, NFC, A-GPS (GLONASS), and an FM Radio.

On the storage side of things, the UK version has 16GB onboard with microSD support for cards up to 128GB. Not a massive amount of onboard space, but should be adequate for most apart from the power users, the card capacity is nice for media aficionados to hot-swap music, image and film collections. A 32GB model does exist but is currently only available in Asia.

At the heart of the phone is Qualcomm’s Snapdragon 801 quad-core chip based on its Krait 400 architecture, specifically the MSM8975AC model clocked at 2.5GHz. It carries an Adreno 330 graphics processing unit (GPU) and again the UK model has 2GB of RAM, while buyers in Asia can enjoy 3GB alongside their 32GB of onboard storage space.

The LG G3’s smooth running interface is one thing but it’s also a dab hand at more intensive tasks thanks to that engine block. It handles high-end gaming such as Asphalt 8 effortlessly and with no performance lag, while multitasking a large number of apps is also no problem. I did notice the handset tended to heat up rather a lot even during relatively light workloads, meaning intensive use turns it into quite the little burner, but that’s not unusual for Snapdragon 800/801 devices by any means.


LG’s gone for a removable 3,000mAh cell, which is handy as it enables hot-swapping of spare packs, if you’re that way inclined. Battery life seems quite variable, I ran our video test with Django Unchained from 100% charge – the film runs 2.45 hours. With full brightness on (bearing in mind this is a massive, high-resolution and ultra-bright display) and Wi-Fi enabled, streaming the film for its full duration ran the charge down to 37%. Not great.

However, re-charging to 100%, pre-loading the film and then running it on the same settings saw the phone come down to a more respectable 50%. Not bad.

That display is no doubt taking a fair share of the juice, but you’ll have to be careful with other power drains if you want to get a decent run from the LG G3. Being careful, it should manage around five hours of continued video playback (pre-loaded), but streaming significantly less.

As expected, I found with moderate to heavy use the handset needed a charge by the end of a working day from 100%. Considering the demand that screen no doubt puts on the phone it’s actually impressive that it manages this kind of performance, which is fairly typical of several high-end devices with generous batteries these days.


As LG’s tech is so often very similar to that of Samsung’s, it should perhaps not be surprising that the camera performance is very reminiscent of what we’ve seen from its fellow Korean phone-maker. By that, I mean that it’s got a clean, easy-to-use UI, and has been calibrated to produce slightly more vibrant images than you might get on sensors which aim for very true-to-life contrast and colour accuracy. That’s not to say the results looks unreal, because they don’t, but they have a lot of pop, meaning there’s little need to use apps such as Instagram if you like a striking image.

The sensor is a 13-megapixel back-illuminated (BSI) setup with a 1/3” sensor size and an f/2.4 aperture. It has a dual-LED two-tone flash, optical image stabilisation (OIS+) and laser autofocus. LG claims the laser autofocus means it’s able to focus and capture a snap faster than you can blink, and this does indeed seem to be the case – it’s very quick on operation. That, combined with its easy UI means it’s great for fast and effortless point-n-shoot purposes while delivering great results.

The OIS+ seems to help too as image quality seems to be a wee bit sharper and more detailed than Samsung’s 16MP ISOCELL, while dynamic range and contrast are both excellent and it handles low-light quite well. The LG G3 supports HDR mode, panoramic capture and voice activation, as well as geo-tagging, face and smile detection, and burst mode. Video capture supports 1080p and 4K Ultra HD quality and is incredibly sharp and smooth, while a 2.1-megapixel front-facing secondary can be used for selfies and video calls in 1080p quality.

If you're interested in how the LG G3's imaging capabilities stack up against key rivals (*spoiler*: it did rather well), head over to our big flagship cameraphone shootout where we put it through its paces alongside the likes of Samsung's Galaxy S5, Nokia's Lumia 1020, and Sony's Xperia Z2, amongst others:


The LG G3 is a really quite impressive device and I’ve enjoyed using it. It has one or two odd little quirks which hamper the experience a bit – for me these have been relatively minor gripes which I’ve been able to cope with, but I can imagine them being more irritating for some users.

Despite some initial concerns during my first hands-on, I think the software experience is great, as I mentioned, there are parallels to be drawn with HTC devices and it’s really just a pleasant UI to look at and operate. A spoonful of customisation options never hurts, and some added functionality, such as the Dual Screen mode and built-in File Manager are most welcome indeed.

I do think the Knock On feature is a bit of a stumbling block though, it just needs better implementation and may annoy more users than it pleases due to its tendency to activate the phone in your pocket. The LG G3 could benefit from more onboard storage, and while the battery life can be quite reasonable, if you’re not super-careful there’s quite a risk of getting caught short. The display, camera and general performance, however, are all superb, as is the design and build. A highly recommendable handset, with a few caveats.

If you wanted to pick up the LG G3 16GB edition you’ll find a bit of a nice surprise, it has had a price cut in certain areas of Europe, including the UK where the price has been dropped from £489.99 to £455. That's the tag you'll currently find on the Amazon UK Store, but a selection of other retailers have also adopted the price cut.

The LG G3 & The LG G Watch

Logically, you'd think that in order to generate interest in the new wearable product there'd be more than a few offers around provided by retailers, networks, and even LG itself, to bundle the LG G Watch in with the LG G3. Sadly, this doesn't appear to be the case, we've only discovered two so far, and one of them leads to a dead page (TalkTalk), so really there's only one - Three UK. It's definitely worth pointing out that the LG G3 will pair with any smartwatch running Android Wear (such as the Moto 360 and Samsung Gear Live), while the LG G Watch will pair with any Android KitKat phone - so this kind of dualling up on LG products isn't strictly necessary, but still, it's surprising not to see more bundles.

If you're thinking of picking up an Andorid Wear smartwatch to pair with your LG G3, the G Watch is one of the cheaper options. Here are some excerpts from our full review (which you can read in full here), to give you an idea of what it's like, and whether it's for you.

"Previous smartwatches made the mistake of trying to include too much functionality, and that isn't a pitfall Google intends to fall into. Android Wear keeps things simple and is primarily a notifications platform. Pretty much every alert or message you could normally get in Android's notification pane is instantly beamed to your wrist, allowing you to view emails, read tweets, acknowledge calendar appointments and digest eBay messages without having to remove your phone from your pocket."

"While Google and its hardware partners have tried to talk-up the stamina of Android Wear devices, we found that around two days is the most we could expect from the G Watch's 400mAh power cell before it started gasping for air. Realistically, you're going to end up charging this watch on a daily basis, just to ensure it doesn't run out of steam mid-way through the day when you're away from a charging point. "

"The G Watch does an excellent job of showing off Google's new wearable OS, so the lack of aesthetic bells and whistles isn't an issue. LG knows the software is the star here. Android Wear makes managing and responding to alerts a lot easier and more intuitive, and we'll no doubt see the platform improve and mature over the next year."

So that Three deal then. Essentially when you pick up the LG G3 with Three UK on a contract, you can get the LG G Watch for £99 instead of the usual price of £169 when bought on its own. Check it out here.

Latest LG G3 News & Info

LG G3 Coming In Two New Colour Choices In August

Currently you can get the LG G3 in either white, black, or gold, or to use LG's funky names; Metallic Black, Silk White, and Shine Gold. However, from August this year there will be two new colour options hitting the market - although as usual there are no specific dates.

LG says it will roll out the new colour options "in select markets in August and continuing over several weeks. Exact colours and dates will be decided locally in conjunction with carriers. Announcements will be made in each market at the time of availability."

In other words, it's not certain these new colour versions will come to the UK, but we'd be pretty surprised if they didn't.

The two new colour choices are Moon Violet and Burgundy Red.

LG G3 Breaks LG Sales Records

The LG G3 appears to be the best selling LG handset to date, with the company revealing on July 24 it has hit record sales figures for Q2.

LG said handset sales had risen by 16% year-on-year, up to $3.5 billion from 14.5 million units shipped. The company didn't specify how many of these handsets were its new LG G3 flagship but did say it attributes most of this boost to its latest device.

Company net profit hit $400 million with revenues across LG totalling $14.9 billion.

Essentially it looks like the G3 has helped LG finally break into the big leagues. It has a little way to go before surpassing Korean rival Samsung, but with the Galaxy S5 apparently falling out of favour it looks as though there's plenty of room for LG to take advantage and move forward.

LG G3 Cracking Problems?

Reports have emerged that some users are reporting issues with their LG G3 handsets, with several devices apparently showing cracks on the chassis following normal use.

Disgruntled users have posted pictures online showing the damage suffered by their devices and it's claimed these have occured through ordinary phone use rather than heavy drops or abuse.

Since these complaints emerged, LG has issued a statement on the subject. Speaking to Trusted Reviews, the company said:

"It has come to our attention that a number of the LG G3 smartphones have developed cracks near the microphone openings at the bottom of the devices. This is in no way related to product design or product quality and only affects a limited batch of devices." "We would like to assure LG customers that the issue has been resolved at its source and ask customers with affected devices to immediately contact the LG Electronics service centre in the country of purchase for assistance. LG would like to thank its customers for their understanding and apologise for any inconvenience this may have caused."

So it would appear it was a manufacturing fault affecting only a limited run of LG G3 devices. At least that's the official story.
