With a qualcomm snapdragon 410, adreno 306 gpu, 2 gb of ram, 2 sim card slots, both of which support 4g, an awesome camera and battery life, and also expandable storage, I can say this phone is the best bang for the buck. It comes with MIUI 6 out of the box. You can upgrade it to MIUI 7. Ive owned this device for about 3 months now and I absolutely love it. I have also flashed CM 12 on it. Rooting doesnt void the warranty either. Its just as fast as it was on Day 1.
I must say, redmi 2 prime is the perfect phone for anybody looking to buy their first device.
At RS 6, 999 I think the price is very well justified.
