This is the best phone I have ever seen in this budget. Compairing to other companies you get more feature in xiaomi company. In xiaomi redmi note 4 you get a huge ram which is 4 gb and a huge internal storage to store more media in your device which is a very good thing about rhis phone.
Gaming performance-
I installed many high graphics game on this device and there is no any lags or hangs on any of the game which is very good thing .
Fingerprint sensor-:
The responce of the fingerprint sensor is very good and I feel very safe when my mobile is protected by the fingerprint security and the security is very good no one crack your security.
