I bought the phone for the 3 months is the oppo a37f, the phone is a lot problem in it. The phone plays a lot of trouble when the phone is playing a small game or installing some apps. On the Internet, the phone becomes very slow. This phone’s battery service and sound quality is very bad. There is no good facilities in this phone, this phone is getting very hot. The biggest problem of this phone is hang problem. This phone is only good with the camera quality and everything else is worse than this phone. Buying this phone means waste of money.
