Oppo f5 is available in very affordable price. It gives the facial unlock in very little money. It’s facial unlocks is working very fast. It detects the face in dim light also. Oppo gives many good and useful features in very small amount. It’s facial is real and my is not opened by any other people’ s face. It is helpful. This phone gives us greats security. Its display is full hd and it works very smoothly. I like this phone very much. In my opinion it is the best phone for the middle class peoles.
