Xiaomi redmi note 4G is a android phone which has MIUI 6 installed, and 2 GB of RAM and 8 GB of ROM. The phone has good camera quality. And all xiaomi phone has there own specific app like - report bug, themes of xiaomi it is great but one problem of xiaomi redmi note 4G is power button ( screen lock button) in the side of it. It is very delicate after use of 6-7 months the power button ( screen lock button) does not work properly and some time it doesn’t work then push the button strongly and after that it will work otherwise it not work. I saw many xiaomi redmi note 4G and all have this type of problem I also use xiaomi redmi note 4G and also face this problem. Other then the phone was very good.
