Informr score
The LG Optimus 2X currently has an Informr score of 7.7 out of 10. This score is based on our evaluation of 26 sources including reviews from users and the web's most trusted critics.

The LG Optimus 2X is one of the new breed of GT cell phones, in this case powered by a dual-core 1GHz NVIDIA Tegra 2 processor, complemented by a 3D graphics hardware accelerator. That's more than twice the processing speed of some of the top-shelf smartphones that have recently been released, plus the added graphics "Umph!" to make this phone capable of handling games, videos and general internet navigation simple and satisfying.

Android powered, the Optimus 2X boasts a 4-inch screen that ponies up 480 x 800 pixels of resolution, features an 8MP camera with LED flash, secondary, 1.3MP camera, HD video record, MP3 player, FM radio, and native YouTube player.

The Optimus 2X ships with a full, robust HTML browser and built-in support for Facebook, MySpace and Twitter. It offers GPS/navigation, WiFi, Bluetooth and the always welcome 3.5mm headset jack. This phone is HDMI capable and offers memory expansion up to 32GB via microSD/microSDHC.

The LG Optimus offers a talk time up to 7.83 hours and a standby time up to 400 hours.

Lets be clear, it's not the Formula 1 car everyone thought it would be. Having said that, it's still one of the fastest smart-phones currently available. It also is running an older build of Android with a laggy LG UI running over it, which is not a good thing. Aside from that there is not much to c...

A few hours with the phone will suffice for the impression to remain forever, regardless of backlight bleeding and bad earphones. We were expecting a high-quality device from LG to begin with, but they’ve still managed to surprise us all with this exceptional smartphone, one of the best, if not the...

Greater and greater processor power has become an important factor with smartphones and LG has presented its first model which uses the NVIDIA Tegra 2 chip. With it, the LG Optimus 2X has topped the market when it comes to performance, but luckily, not when it comes to the price. Due to thi...
