-As expected, the new version stays fairly close to the successful formula of the original. The screen keeps the 4.7" diagonal, but the Redmi 2 is marginally more compact.
The screen itself comes from Sharp and is a 720p IPS unit with 312ppi. Xiaomi has enabled color temperature adjustment.
-Inside is a Snapdragon 410 chipset - quad Cortex-A53 at 1.2GHz, 1GB RAM adn Adreno 306. The software has been upgraded to MIUI 6, Xiami's customized Android distribution. There's 8GB of built-in storage, expandable with 32GB microSD cards.
-The camera department didn't get much of an upgrade. The main camera of the Redmi 2 is an 8MP shooter from OmniVision. It has a 28mm wide-angle lens with f/2.2 aperture and can shoot 1080p video. On the front is a 2MP/720p camera.
The Xiaomi Redmi 2/Hongmi 2 will launch in China on Friday (January 9) at CNY 700 - that's just $110. There is no official info on when availability will be expanded to other countries.
