Sounds like there might have been a program on your previous 600 that you might have installed from the backup folder by accident. I would recommend doing a hard reset, but instead of installing directly from your backup folder, moving that folder to another location on your hard drive and then installing apps back one at a time.
Before syncing any apps, you could then check that issue with turning the phone app on and if it still happens, it would seem that your replacement was "played with" and you might/should merit another replacement. |
