How to backup calls on Android, there is an app in the Android Market to help backup and restore call logs to another phone or after a complete reset. A small application, but very useful.
Call Logs Backup & Restore is a free application that lets you do exactly what it says. You create a backup copy of the call logs and you can easily restore them again later on the same phone or a new phone.
I tried this on my Galaxy Tab S4 and Samsung Galaxy S9 – everything worked perfectly! Install the app from the Android Market. Then, in the app, click on the ‘Backup’ button to start the backup process. The backup process has never been easier!
