    • Perform a factory data reset. This is sometimes the best solution if your device stops functioning properly, but note that it will delete all personal content saved on the internal memory of your device. Make sure to back up data that you want to keep.

      To back up your data using a computer

      1. Unlock the screen of your device and connect your device to the computer using a USB cable.
      2. On the computer, select which files to back up, then copy and paste or drag and drop the files to a location on your PC.

      To back up and synchronize apps, phone settings, and call history

      1. Find and tap Settings > System > Advanced > Backup .
      2. Tap the switch to enable the function. Your app data, device settings, and call history will be backed up automatically.

You can synchronize your app data, device settings, and call history automatically by logging in to the Google account used to synchronize data on your old device. When you power on your new device for the first time, log in to the Google account during the setup wizard.

      To perform a factory data reset

      To avoid permanent damage to your device, do not interrupt a factory data reset procedure.

      1. Back up any important data that is saved on the internal memory of your device to a memory card or other non-internal memory. If you have any encrypted files stored on an SD card, you should also remove the encryption to ensure you can still access them after the reset.
      2. Find and tap Settings > System > Advanced > Reset options .
      3. Tap Erase all data (factory reset) > Reset phone .
      4. If required, draw your screen unlock pattern or enter your screen unlock password or PIN to continue.
      5. To confirm, tap Erase everything .

      Your device does not revert to an earlier software version of Android when you perform a factory data reset.
