Factory Reset Protection

Factory Reset Protection (FRP) is a new feature in some of the devices with Android OS 5.1 or higher. FRP prevents other people from using your device and performing a factory reset without your permission. Factory reset in that case is only possible with access to your Google Account and screen lock information.
