Back up data on an Android device

    A master reset is sometimes called a factory data reset or reset for short. It restores the phone to its original settings, as if it is new again. This deletes the information stored on the device. Information stored on the memory card or synchronized to a Google account is usually saved, though some devices erase the memory card. Follow these steps below to back up any data that you may lose.


    If you need help performing any step, check the how-to guides for your device on the Phones page.



    Sync your account, calendar, contacts, and email

    1. From the Home screen, press the Menu key.
    2. Tap Settings.
    3. Tap Accounts & sync.
    4. Look for a Google account (as well as any other email addresses):
      • Write down the account names, and remember your passwords. You will need them to log in after the reset.
      • If you do not know your password, go to from a computer.
    5. Touch Sync all button to back up your synchronized data.
    6. After the sync instructions above, you can check calendars are backed up:

      1. From a computer, open your calendar on or Microsoft Outlook.
      2. Make sure all your calendar items appear.
    7. After the reset, log in to the accounts and sync the phone to restore contacts and other info.




    Paid applications are already saved to your Google account.


    If the app stored data (save games, high scores, memos, preferences, etc.) on:

    • The memory card, then the data will be saved.
    • The phone memory, then the data may be lost.


    There are non-T-Mobile applications on the Play Store that can back up your app data. T-Mobile does not support these applications, but you can contact the developer for help.




    Android devices may save your media (pictures, photos, videos, music) on the SD card. If it is stored on the internal storage, you can move it to the SD card or a computer.
