As this OS is not from Samsung and there are many hurdles I don't expect sync to work as nicely as it could. That is we would have to cover this from app to app and if the OS version differs then I expect no success here. That doesn't mean we can't look at other sync methods but as this is volunteer I think you are going to have to make a choice. That is, ask others to discuss Android sync issues and ideas or just make it a warranty issue and demand Samsung make good.
My girlfriend just got a Samsung Galaxy Note (2014 edition) and wanted to restore from her Samsung Galaxy S3 backup. She has her S3 configured to auto-backup, and she set up her Note with the same Google e-mail address and password. However, when she goes to Settings > General > Cloud and taps on "Restore from backup" (or whatever the option's called; I can't remember right now), it says "Recovering information..." or "Looking for data..." or something to that effect, stays there for a while, and eventually stops trying. What are we doing wrong?
Also, once she's successfully restored from backup, how can she set her S3 and Note up so they auto-sync whenever theyre connected to the internet?
Thanks for any help!
