LG G2 full review

Samsung Galaxy S4 vs LG G2 comparison review

LG has never made any really significant waves in the smartphone market (excluding the Nexus 4), but it aims to change this with the new LG G2. It will take on the big guns including Korean rival Samsung so we take a look at the two in our Samsung Galaxy S4 vs LG G2 comparison review.

If LG wants the G2 to be a success it will have to take on, among others, Samsung's flagship Galaxy S4. We've put the two side-by-side across different areas. See also: The 8 best smartphones: What's the best phone you can buy in 2013?

Samsung Galaxy S4 vs LG G2: Design and build

The Samsung Galaxy S4 and LG G2 look like very similar smartphones. They have very closely matched dimensions and both use a plastic rear facia. Despite having a larger display, the LG G2 is only a couple of millimetres bigger than the S4 thanks to some incredibly small bezels.

Although you might not distinguish them at a glance, there is one key design difference. While the Galaxy S4 has its classic home buttons, touch sensitive buttons and others on the sides, LG has gone for an unorthodox approach. It's buttons are on the back of the device below the camera - LG calls it the Rear Key.

Samsung Galaxy S4 vs LG G2: Screen

Screen technology is increasingly an important factor in a smartphone, it really is like carrying around a mini TV now.

It's extremely nip and tuck between these two in this area with the LG G2 offering 0.2in more than the Galaxy S4 without the phone being significantly larger. The both carry a Full HD resolution meaning that it's the Samsung has the higher pixel density count. The difference is minor and not something you'll actually be able to notice.

More important than pixel density is the screen tech used in each device. Put under a microscope, the LG G2 uses an IPS+ panel which offers a more sub-pixels which are in a more uniform array than Samsung's SuperAMOLED.

The difference is also noticable in terms of colours with SuperAMOLED often put down for looking unnatural and over-saturated while IPS is more natural.

Samsung Galaxy S4 vs LG G2: Processor, memory and GPU

On paper things looks similar here but the LG G2 wins in a few different ways.  For starters, it has a newer generation Snapdragon 800 compared to the S4's Snapdragon 600 with a faster clock speed and Krait 400 cores over Krait 300.

Each has 2GB of RAM but the LG G2's memory is faster at 800 Mhz. Moving onto the GPU and again, it's new and more powerful generation Adreno 330 against the Galaxy S4's Adreno 320.

Benchmarks we've seen show the LG beats the Samsung comprehensively despite the allegations that the S4 cheats at some tests.

We'll post our benchmark results as soon as we get our LG G2.

Samsung Galaxy S4 vs LG G2: Storage

Samsung usual outdoes its rivals when it comes to storage and this battle is no different. The Galaxy S4 has more capacities on offer (although good luck finding the larger ones) and has a microSD card slot for expansion which the LG G2 disappointingly does not.

Samsung Galaxy S4 vs LG G2: Cameras

Cameras are another area in which things are very close, on paper at-least with only 0.1Mp in it. You can expect both smartphones to take excellent photos and videos (the Galaxy S4 is probably the best we've reviewed to date).

However, if this is an important area for you, then the LG G2 has a trick up its sleeve which might sway you. Like some of Nokia's phones, it has optical image stabilisation which means you'll get low-light shots with less blurriness and video with less jerkiness.

Samsung Galaxy S4 vs LG G2: Software

Both of these smartphones run Android 4.2 Jelly Bean despite version 4.3 having been launched recently.

Samsung slaps its TouchWiz interface over the top of sock Android and LG's latest effort is called Practical UX. They look surprisingly similar, each bundling extra software features which you won't find on other devices.
They're quite varied – you'll probably find some a daily help and others nothing more than a gimmick. It's worth trying out each so you know which you prefer.

Something to note, although not strictly software, is that the LG G2 supports 24 bit/192 kHz audio playback – one for all you audiophiles out there.

Samsung Galaxy S4 vs LG G2: Connectivity

Things are dead heat on the connectivity front. Both the Samsung Galaxy S4 and LG G2 offfer 4G LTE network support, dual-band 11ac Wi-Fi, Bluetooth 4.0, NFC and Infrared, DLNA and A-GPS.
