Hello,
I just factory reset my z3 because stamina mode wasn't working and I wanted to give it a go to see if factory reset would work. I used the built in Backup and Restore app to backup my messages (conversations) to my SD card (everything else was backed up through Google already). Well, every time I hit the restore option it finds the file and acts like it is restoring, only to leave me with nothing. And every time I reset my phone it alerts me that a backup is detected and wants to do a restore.
Any ideas?
