Back up or restore data on your Android device

You can back up content, data and settings from your phone to your Google account. You can restore your backed-up information to the original phone or to another Android phone.

Restoring data varies by phone and Android version. You can't restore a backup from a higher Android version onto a phone running a lower Android version.

Note: Some of these steps work only on Android 9 and up. Learn how to check your Android version.

Back up data and settings

To help protect your backed-up data, use a PIN, pattern or password screen lock, instead of a swipe or Smart Lock.

What gets backed up

Backup services differ.

If your backups are uploaded to Google, they're encrypted using your Google account password. For some data, your phone's screen lock PIN, pattern or password is also used for encryption.

If you back up to Google Drive, here's what's backed up:

  • Contacts
  • Google Calendar events and settings
  • Wi-Fi networks and passwords
  • Wallpaper
  • Gmail settings
  • Apps
  • Display settings (brightness and sleep)
  • Language and input settings
  • Date and time
  • Settings and data for apps not made by Google (varies by app)

Note: Not all apps can back up or restore all settings and data. To find out about an app, learn how to contact its developer.
