I got my phone around november 10, 2012. I came from iphone so i didn't know much about android, still rooted and such. had some trouble with the phone, but eventually fixed it. when I had custom roms installed, my phone always crashed like "unfortunately, _(insert anything here)___ has stopped working" so i came back to stock rom ICS 4.0.1. it was so clean and didn't have any problems. couple days later, I installed JB 4.1.1, and now everything, again, crashes. I tried "factory reset" numerous times and it actually made it worse... going into the safe mode, fixing weather widget, or clearing data really didn't help that much. anyone know how to resolve this problem?!
