7.6.6. Back Up your Contacts
We use our phone on a regular basis and it is best to back up contacts so that you
can easily restore them or use them on another device.
Use the built-in backup tool. Go to [Settings] > [Additional Settings] > [Back up
and reset], then tap [Backup and Restore]. Back up your contacts. You need to make
a copy of the existing backup file and move it to another storage device.
