ok, so I'm not very good with tech, however, I have had silly amounts of problems and issues with Samsung cloud, one drive, and google back up... I did the latest Samsung update on my 2 month old phone and since then my screen has been playing up bad, so, I backed up everything to Samsung cloud, one drive and my Google account, I had automatic backup selected anyway but I wanted to ensure I didn't lose anything so I clicked back up on them all anyway, it said that everything was backed up, so all ok..right?? Wrong!! I did the factory reset and then tried to put everything back on my phone, and nothing was there to restore back to my phone. iv lost everything, yet when I did all of the back ups, I checked that it had all been uploaded to the cloud, one drive etc., and it had, I backed up to all of them to make sure that I didn't lose anything, yet, I lost it all anyway. iv researched this, and alot of other Samsung people are experiencing the same problem. and with screen problems, all since the last update. so be careful about how and where you are backing your things up to.
samsung are apparently not taking responsibility for issues with the update problems. I'm so upset about it all. take care, good luck.
