SpecificationsEdit

SoftwareEdit

The Redmi 2 comes preinstalled with Android 4.4 KitKat with the proprietary MIUI 6 custom graphical user interface, it can be upgraded to MIUI 9 via OTA. The Redmi 2 comes with a factory-unlocked bootloader, allowing users to "root" the device and install custom firmware.

The software-development community has released custom ROMs and kernels for the phone, even though the official kernel sources from Xiaomi were only released a year after launch.[3][4] The Redmi 2 has achieved unofficial stable builds of CyanogenMod 11 (based on Android 4.4), 12.1 (Android 5.1) and official nightly builds of CyanogenMod 13.0 (Android 6.0.1) and CyanogenMod 14.1 (Android 7.1.1)[5][6][7][8] Development of the latter version is continued in the LineageOS project after CyanogenMod's discontinuation.[9]

HardwareEdit

The Redmi 2 is powered by a 1.2 GHz Snapdragon 410 SoC with Adreno 306 graphics engine. It features 1 GB of RAM and 8 GB of storage. The Redmi 2S, also called Redmi 2 Pro or Prime (depending on locale), has 2GB of RAM and 16GB of storage.[10] The display is a 4.7 inch IPS panel with touch capabilities, 1280x720 resolution at a density of 312 ppi with scratch-resistant AGC Dragontrail glass.
