Cvele99, Dec 9, 2017 : Here is the problem. My phone has suddenly restarted, and every time it starts up, home screen is empty (maybe once every 10 restarts I see home apps) and notification pops on the screen: "Unfortunately, Trebuchet has stopped working.". A few other notifications pop up also, saying that some other apps have stopped working as well. After I close those notifications, they just keep popping up. Whatever I try to do, the phone restarts itself after 10sec – 1min, and it goes like this forever. I googled up that I should go to Settings->Apps->Trebuched->Force stop, but every time I manage to reach Apps tab, notifications "Unfortunately, Settings has stopped working." pops up. I haven't tried to do a factory reset because I have data from last ~6 months on it. Is there any way to fix this without loosing data on the phone? Or is it possible to fix this at all? Any help would be really, really appreciated.
