after I update my s4, I faced some problems as battery and keyboard, but camera wasn't had any problems.
yesterday and suddenly when I take some pictures, the camera resolution become very very poooor. although I am very careful about my mobile, and never fall or break forum my hand.
also device temperature rise when I used it or when I connect it to my laptop, specially in the area under camera and in the screen.
I restored mobile to factory reset, but nothing changes.
