How to reset your Android phone to factory settings

Restoring your Samsung® or Google® phone to its factory settings helps protect your personal information when you do the following:

  • Sell your phone.
  • Trade it in for a new device.
  • Give your phone to a friend or family member.
  • Need to troubleshoot performance issues, such as a frozen device or forgotten passcode. Our experts only recommend this as a last resort, after you’ve tried everything else.

A factory reset deletes nearly all data on your Android phone, giving it a clean slate. That’s why it’s important to make sure you’re prepared to take such a big step. It does more than reset your device settings and accessibility settings, here’s what a factory reset deletes from your phone:

  • Contacts
  • Photos and videos
  • Music
  • Passwords and files
  • Accounts
  • Messages

Before you restore your Android to factory settings, there are important steps to take to make sure you don’t lose your existing data.

  1. Back up your Android phone. The first thing you should do is back up your phone. Uploading it to a service like Google Drive™, or one offered by your phone carrier, will ensure you don’t lose everything during a factory reset.
  2. Plug your Android phone in and connect to Wi-Fi. The backup process can be time-consuming, so you’ll want the power boost. It’s also best to save your files over a secure Wi-Fi connection so you don’t use up a lot of mobile data during the transfer.
  3. Know your login info to restore data after resetting your Android. Before you reset your phone, make sure you know your login information. A Google Account username and password are required to restore data on an Android device—you can typically find your Google Account in Settings.
  4. Unpair your Android device. Be sure to unpair or disconnect Bluetooth® devices like your smartwatch or wireless headphones.
  5. Sign out of all accounts. Protect your privacy by signing out of all your apps, services, and email accounts and also delete any cards you have saved in your mobile wallet. You should also turn off Find My Device—check out our guide to learn how.
  6. Remove your SIM card. Check out our guide to removing your SIM card from your Android device for easy-to-follow steps.
  7. Sign out of your Android phone. After backing up your data and completing the checklist above, don’t forget to sign out of your Android phone too. Although a factory reset removes all the information stored on the device, this will ensure no one can access your account after you sell or trade in your phone for another one.

You can usually perform a factory reset in Settings, but it can take up to an hour to complete. Make sure your phone is plugged in while you’re going through the factory reset process.
