How to factory reset your Android phone
Start by backing up your Android phone, then remove the MicroSD cards and your SIM card. Remember to use the backup feature in specific apps (like WhatsApp) and transfer codes from apps like Google Authenticator.
Android has an anti-theft measure called Factory Reset Protection (FRP). It means that even after erasing an Android phone, you will need the last Google account login to set it up again. It should only activate if you use the recovery menu to wipe your phone, but here’s how to disable FRP anyway. Delete your Google account (we recommend deleting all your accounts at the same time). Different Android manufacturers have slightly different menus, so your options may vary.
On a Google Pixel, you can do this on Settings touching Passwords and accounts. Select each one in turn and tap Delete account. On a Samsung Galaxy, go to Settings and select Accounts and backupso Management accounts. Select each one in turn and tap Delete account.
You can now erase your Android phone, but this process is also slightly different depending on who created your phone. On a Google Pixel, for example, go to Settings > System > Reset Options > Erase all data (factory reset) > Erase all data (you will need to enter your PIN) and finally Delete all data again.
On a Samsung Galaxy, go to Settings > General Management > Resetand choose Factory data reset. Scroll to the bottom and tap Restartso Delete all (You may need to enter your Samsung account details.)
Other Android phones will have similar options to what we’ve listed here, but if you can’t find them, head to the manufacturer’s website to find a guide.
That’s all. Your device is ready for the next phase of its life. Here are some ideas on what to do with your old phone. You can even try setting it up as a security camera!
