Before performing a factory reset on your phone, we would recommend backing up to ensure no data or downloads are lost.
Option 1: Back up to a Google Account
Go to Settings > System > Backup > Enable and select Back up Now.
Note: Make sure the relevant files and apps are being stored by enabling these within Backup details.
Option 2: Back up to PC / External Storage
- Connect your device to a PC or an external drive using a USB cable.
- Make sure your phone is unlocked and pull the notification bar down.
- Tap on Android System • Charging this device via USB. Under USB Preferences and USE USB FOR select File transfer. You will now be able to access your phone's folders on your PC.
- Select the files you would like to save and store on your PC or external drive. Those can then be transferred back to your phone after the factory reset is complete.
