This is the best phone under 10000 rupee, I purchased the same from official site of mi india( and also uploaded video of the same on youtube. The only problem is that if you play lots of games, then heating may occur due to 430 snapdragon processor, rest everything is good in this phone. Although phone does not support 4K video, but still I tried to make same phone and uploaded on youtube.
I am able to make photo sphere also, due to presence of gyroscope in this phone. Xiaomi Redmi 3S Prime support VoLTE, so that you can also use Reliance JIO Sim in this phone.
