My daughter has an S3 on Virgin Mobile USA. At one time she had (I think) 5 home screens set up. Over the past month or so, they have been slowly disappearing without her removing them, and as of today, she has only one remaining. Because the charging port is bad, she has an extra battery which charges externally. The phone is powered off every day when she swaps batteries, and it appears that the extra screens have disappeared when the phone has been power cycled. Any idea why this is happening? Obviously the screens can be re-added, but it seems like a lot of work to go through if they are only going to keep disappearing. She does plan to get a new phone, but can't afford one yet, so she wants to make this one last as long as possible.
