Is it possible to backup the Sony music app or data settings so that when installing apps onto a new mobile the music data settings such as artwork and track details are synced to the music app on the new mobile?
Don't know if it's a bug or not but if you move an album folder from say the external drive to the Internal drive, once you open the music app again the track numbering and album art go back to how they were with the older mobile.
Hope I've explained that enough.
