Read: LG G3 release date, price, specs and price UK.

Full HD is now officially out of date on smartphones with the G3's whopping pixel density of 534ppi, the highest we've ever seen on a mobile device. We'll have to see what LG's rivals come up with later this year.

The screen is a large 5.5in but once again LG has done an amazing job of keeping the device as small as possible. For example, it's not as tall as the 5.2in wielding Sony Xperia Z2.

Other key features of the LG G3 include its metal finish which isn't like the HTC One M8's. Instead, the plastic removable rear cover has a metallic skin which a brushed finish. It's not particularly nice on the white model we've got but we like it on the other colours.

That cover also adds wireless charging to the device which is something still quite rare for a smartphone these days. See also: 27 best smartphones: The best phone you can buy in 2014. 

The camera resolution stays the same when compared to the older LG G2 at 13Mp but there's new features here including 4K video recording, a dual-tone flash and a laser auto focus.

Android 4.4 KitKat is onboard and you can check out LG's overhaul graphical user interface in the video.
