I have a weird problem with my Note 2. I got my phone out of my pocket to check the time and it was on the Android setup page (choosing language, gmail, etc) and it was also unresponsive and kept freezing. After that the apps on the home page were gone. Not only that but when I opened the apps, data was not saved as it was like a new app. Firefox and some other app kept saying process not working.
I am on Android 4.1.2 stock with Persius kernel. I am not sure if it has to do the Sudden Death syndrome as I have an insane chip or the fact it was an update with a certain app. Please help me.
