Hello. I have a Samsung Galaxy Ace GT-S5830M. Today I was using my phone. Everything was working well. When I came home, I put it to charge then I went to take a nap. When I woke up and checked my phone, none of the apps were responding. sometimes this happens, and usually this problem is solved when i restart the phone. so i did this and this only made things worse. after restarting the phone, not only did none of the apps work, the android software itself stopped working. I have lots of pics from my vacation on the sd card and i am not sure if to do a factory reset for fear of losing these. what should i do?
