Recent news events have indicated that some models of an Android device do not actually erase the data when you do a factory reset. That’s a problem if you want to sell or donate your device and don’t want any of your personal information to be donated too. The factory reset problem doesn’t impact every Android device, but how would you know if your data really is gone? The Verge has a simple solution to fix the problem. Make sure your phone (or other device) is encrypted first and then perform a factory reset. My obvious question is…why isn’t your phone already encrypted? Suffice to say, encryption is your friend and should be enabled on all devices, including mobile ones.
