Android Factory Reset Protection
What are the pros and cons of Android factory reset protection? This is a new feature that is included with Android version 5.1.1. First, I have to state that any security measures that can be added to your android device will only improve the safety of your personal data. That being said, you as the owner of the device, should also have the option and control to turn these features on and off as you choose. For example, unlocked bootloaders, carrier unlock, factory reset protection, and Write Protect to name just a few.
1. Device will not even boot to lock screen without the correct password. Kernel level password check.
2. Using Android device manager, you can remotely locate and/or wipe the data on your device.
3. If your device is lost, stolen, or wiped, only someone with your Google account or screen lock information can use the device.
1. Device protection is automatically turned on when you add a Google account and setup a lock screen password. I list this as a con because it is automatic.
2. If you have Factory Reset Protection turned on and you mess something up, it will not boot or you forgot your password, then you will also not be able to reset it in stock recovery. The only way to fix this is to use a tool like odin, rsd lite, fastboot, or lg flash tool to restore the factory firmware.
3. If you can’t provide your Google account information during the setup process, you won’t be able to use the device at all after factory reset.

Important: If you reset your Google account password and need to do a factory reset, you need to wait 72 hours after changing your password to reset your device. This is for security purposes.
