i'm using my P9000, unrooted, with the latest Android 6 Stock-Rom and because I want to flash the new Nougat-Rom I tried to save my
Personal and App-Data by using the Stock-Rom Backup- and Restore-App.
Data saving works fine. Just a moment I see the spinning circle and then there appears a list of the installed apps with a checkbox in front of them.
After checking / unchecking the apps and touching the save button, I'm asked where to write the backupfile and a little time later my mobile says that the backup is done. Backup (and restore) od APPDATA works fine!
But when I try to save my Personal Data there the backup process seems to stop at the spinning circle. Even after an hour, it's still rotating!
Starting the backup after phone is freshly rebooted, nothing changes.
