My Galaxy note 9 is playing up. Seems to be some sort of software malfunction so I need to do factory re-set. can't make or receive any phone calls. Internet seems to be ok. How does keeping Line contacts work? Whatsapp are by telephone numbers so will be in the contacts list. But Line you have no way of knowing the Line id unless you happened to have made a note of it. What is the process, if there is one, for saving or backing up Line contacts and chat.

In Line go to settings (top right symbol on main page). It will come up with a page that says Personal info and Backup and Transfer...the 3rd item under "Backup and transfer" is "Account transfer options".

And there you have it. Follow directions.
