Backup and Restoration

Data Backup to a USB Storage Device

If you are running out of storage space on your Phone or you want to back up your important data to
an external storage device, you can connect your Phone to a USB storage device using a USB OTG
cable and back up your data to the storage device. USB storage devices compatible with your Phone
include USB flash drives, card readers, and devices with an Memory card inserted.
Open Settings, go to System > Backup & restore > Data backup > External storage > USB
storage, then touch BACK UP. On the Select data screen, select the data you want to back up and
touch Back up.
You can enable Auto-backup on the backup page. If your device has more than 75% of the
l
battery's capacity left, the system will automatically back up the data when the screen is off.
You can go to
l
on the backup page, and then set a password when prompted. The password will be used
when you want to restore files later. Always remember your backup password or set security
questions to help remember the password as you will not be able to retrieve your backup files
without it.
