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 some other Android phones.  

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.
