Redmi 1s is one of the best phones I have.
Plus point:
Best camera with 8MP and best appearance
Minus:
Our voice is very shaky during calls and its breaking always. Phone generates heat within 1/2 n hour of continuous usage.
I love this phone, from last 1.5 year I am using this mobile from nov14 and there is no technical problem with this phone. Only problem is overheating
For 1 yr usage it is a very good phone.
Worth the price.
