Yesterday when I randomly checked my phone, all my texts were gone, and my home screen was cleared, like it was new. When I try to open anything, it always says that google play store (along with zedge, maps, navigator, etc. just one after the other) has stopped and prompts me to force close. I have already factory reset my phone (voluntarily this time). All I can do is call, and occasionally send a text. I haven't downloaded anything recently, and when I do try to delete apps, they will reappear. What can I do to fix this?
