Panicking over Android’s factory reset is (mostly) unwarranted

Android has a built-in way to fix this problem, though—users can just encrypt the phone before erasing it. Android has a built-in disk encryption feature that can be turned on by going to settings, security, and “encrypt phone.” Since it’s encrypting the entire phone (other than the SD card, which you can just keep), it will take a while to finish.

Android phones aren’t encrypted by default? #fail
