The G2's bezels are the thinnest we've seen so far on a smartphone, almost the entire front of the device is occupied by the large 5.2-inch screen. Unfortunately the screen is very prone to glare which makes framing your shots in bright sunlight a little difficult.

With its 13MP CMOS sensor and an optical image stabilization system, in terms of camera hardware the LG G2 is a clear improvement over the Optimus G that had to make do with an 8MP sensor (13MP in the U.S. Sprint version) and no OIS. However, the G2's imaging module still relies on a small 1/3-inch sensor while some manufacturers have started using larger sensors in their top-end models, for example Nokia with its 1/1.5-inch sensor in the Lumia 1020 and Sony with a 1/2.3-inch chip in the Xperia Z1.

The G2's F2.4 lens is also a little slower than the F2.0 and F2.2 variants of some competitors although you'll struggle to notice much of a difference in daily use. All the other components you find in the G2 are in line with what you can find on other current top-of-the-line Android devices. The Android 4.2.2 OS is powered by Qualcomm's Snapdragon 800 processor and 2GB of RAM. You can choose between versions with 16 and 32GB of storage. To make sure you can use your G2 extensively all day long it comes with a large 3,000mAH battery.

The back of the device comes with a carbon fiber effect but overall the G2 doesn't have the same premium feel as some of its competitors. 
At the bottom of the device you'll find the USB connector, headphone jack and the speakers.

The headline feature though is the large 5.2-inch IPS LCD display with a 1080p resolution. Despite the size of the display the G2's overall dimensions are no larger than those of its 5-inch competitors, thanks to extremely thin bezels which mean that almost the entire front of the device is occupied by the screen. The latter is very bright and offers decent viewing angles but we found it hard to see in bright light which makes framing a shot on a sunny day a little difficult.

While the overall size/screen size ratio is arguably the best we've seen so far on a smartphone the overall finish of the G2 looks and feels a little plasticky next to some of its competitors. By no means does the G2 feel cheap but it doesn't give you the fuzzy "premium device" feeling you get from holding an Apple iPhone 5s, Sony Xperia Z1 or HTC One. 

In terms of device ergonomics LG has taken a radical step to differentiate itself from the rest of the Android bunch and has removed all buttons and keys from the edges of the phone. The G2's external controls are limited to a power button and +/- volume keys, all of which are located on the rear of the phone just below the camera lens. The reasoning here is that when holding the phone in portrait orientation, this is precisely where your index finger naturally falls.

This is arguably true but when you're used to side front/side power buttons it takes some getting used to and I found myself fumbling for the power button on a regular basis. You can't help but get the impression that LG is trying to fix something that isn't broken, just for the sake of differentiation.

All of the G2's controls, power button and volume rockers can be found on the back of the device, just below the camera lens. The volume buttons can also control the shutter or zoom.
The idea is that when holding the phone in portrait orientation, the location of those buttons is precisely where your index finger naturally falls.

With the power button on the back of the device it is not accessible when the phone is lying on a desk or any surface for that matter. But you can therefore wake the phone up from sleep mode by double-tapping on the screen and once you've found the right "tapping speed," this works quite well. In the camera app the volume buttons can be configured to work as a physical shutter or zoom rockers but since they don't offer a "half-press" the advantage over an on-screen shutter button is limited. They also give you quick access to the camera app from the lock screen.
