Also did the update, but honestly it seems like a hardware problem if it was software more people would have experienced it. Went to MTN today and they said they will replace it when they have stock on Tuesday. If the new one also breaks then Ill repeat the cycle indefinitely
Edit, I did a hard reset, restarts and even re installed 4.2.2 using Odin and nothing.
Thanks for this feedback. Think I am going to head over to Cell C.
I didn't flash firmware on my unit, but I did do factory resets and a few short codes trying to check camera firmware and what not. Couldn't get it to work properly.
