Xiaomi Redmi 2 is a Smartphone by Xiaomi released in January 2015.[1] It is the successor to the Xiaomi Redmi 1 family.

Features

The Xiaomi Redmi 2 is powered by Qualcomm Snapdragon 410 Chipset and comes in 2 variants, a normal version which packs 1GB RAM and 8GB of user memory and an enhanced version which packs 2GB RAM and 16GB of user memory.

Software

The Redmi 2 offers Android 4.4 KitKat with proprietary MIUI v6 custom graphical user interface pre-installed by the manufacturer and can be upgraded to MIUI v9 via OTA. The Redmi 2 comes with a factory-unlocked bootloader, allowing users from the outset to further develop the OS and "root" the device, or gain legitimate privileged control in Android's subsystem.

The software-development community has released custom ROMs and Kernels for the phone, even though the lack of any kernel sources provided by the manufacturer. The kernel sources were released a year later.[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]

Display

The Redmi 2 has a vibrant 11.9 cm (4.7") IPS panel fully laminated display with 1280x720 HD resolution at 123 pixels per cm (PPCM) or 312 PPI. It has also 178° In-plane switching (IPS) technology which delivers stunning color consistency from almost any angle. It is also designed with a fully laminated display which allows pixels to sit close to the glass, so colors pop right off the screen and are less affected by glare.

All of this is protected with a highly shatterproof and scratch-resistant AGC Dragontrail glass that is known for being incredibly strong despite being very thin and light.

Hardware

The Redmi 2 is powered by a 64-bit Snapdragon 410 Quad-Core clocked at 1.2-GHz with Adreno 306 graphics engine which supports OpenGL ES 3.0 and DirectX.

It has a Cortex-A53 processor which has up to 50% faster CPU performance than its predecessor, the Cortex-A7.[10]
