BARCELONA: LG was the first to announce a device running the Nvidia Tegra 3 quad-core processor and the handset has been on show at Mobile World Congress (MWC).
The 4X HD boasts a 4.7in display with a resolution of 1280x720. Picture quality has always been a strength of LG devices and the 4X continues this trend by delivering a crisp, clear and bright picture.
Design-wise, the Optimus 4X HD is simplistic, with the screen taking up most of the front. The razor thin bezel is jet black, and the back comes with a mock leather coating to help make the handset comfortable to hold. There are three capacitive touch buttons retained underneath the display, which are barely distinguishable.
Despite Google scrapping these buttons in favour of on screen context sensitive keys, many manufacturers including LG have decided to keep them on.
In terms of specifications, the 4X shares a lot of characteristics with the HTC One X, which was also launched at MWC. Both devices have a 4.7in display with a 1280x720 resolution, are powered by the Nvidia Tegra 3 quad-core processor and have 1GB of RAM.
Unsurprisingly, we found there to be little difference in performance between the two devices. Both are super smooth when it comes to app transitions, loading up web pages and gaming, but only a full scale head-to-head will reveal which one is thb.
Handily, LG was running a developer tool on the devices to show exactly how the quad-core processor works. These were in the form of little percentage bars in the top left hand corner of the screen.
When carrying out low intensity tasks such as the swiping through home screens, only the companion core is used. The full quad-cores kick in when resource hungry apps such as games or videos are initiated. This is likely to be a very useful tool for developers.
LG ships the device with Android Ice Cream Sandwich and a minor overlay that aims to give the handset a little bit of differentiation, without being too overbearing.
The 4X also features 16GB of internal memory and an 8-megapixel camera with a Backside Illumination sensor (BSI), so taking pictures on the move shouldn't be a problem. An 2,150mAh battery is included in an attempt to keep the display and the quad-core processor running all day long.
There's been no official word yet on pricing, but the device is expected to launch soon and given the specs it could be around a similar price to high-end Samsung devices.
