Oh man, errors like this definitely make the phone impossible to use properly serdargozutok. I'm curious, where did you get this phone? I'm guessing you didn't try changing the software yourself, right? You could try a Master Reset with the hardware keys to see if that helps. If it's still under warranty, it may need to be replaced.
Hey there! I just wanted to reach out and see if you'd had any luck with the Master Reset. How is everything going?
