KOREAN PHONE MAKER LG was the first company to announce a smartphone with the quad-core Nvidia Tegra 3 processor and it's proudly showing that Optimus 4X HD handset off at MWC.
The Optimus 4X HD boasts a 4.7in display with 1280x720 resolution. Picture quality has always been a strength of LG devices and the Optimus 4X HD 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 underneath the display that are barely distinguishable.
Despite Google scrapping these buttons in favour of on-screen context sensitive keys, many Android smartphone makers including LG have decided to keep them.
In terms of specifications, the Optimus 4X HD shares a lot of characteristics with the HTC One X, which also launched at MWC. Both devices have a 4.7in display with 1280x720 resolution, are powered by the quad-cor Nvidia Tegra 3 processor and have 1GB of RAM.
Unsurprisingly, we found there to be little difference in performance between the two devices. Both are super smooth with app transitions, loading up web pages and gaming, but only a full scale head-to-head comparison will reveal which one is the best.
Handily, LG was running a developer tool on the device to show exactly how the quad-core processor works. These showed little percentage bars for each processor core in the top left hand corner of the screen.
When performing low intensity tasks such as the swiping through home screens, only the companion core is used. The full speed quad-cores kick in when resource hungry apps such as games or videos are run. This is likely to be a very useful tool for developers.
LG ships the device with Android 4.0 Ice Cream Sandwich and a minimal user interface overlay that aims to give the handset a little bit of differentiation without being too overbearing.
The Optimus 4X HD also features 16GB of internal storage and an 8MP camera with a Backside Illumination sensor (BSI), so taking pictures on the move shouldn't be a problem. A 2,150mAh battery is included in an attempt to keep the display and the quad-core processor running all day long.
LG has not revealed pricing, but it expects to launch the handset soon and given the specifications it could be around the same price as high-end Samsung smartphones. µ
