When I use the Camera app of my GT-S7562 handset , the screen sometimes flickers. Is the device faulty?
The case of flickering is not faulty.
The GT-S7562 has a feature called as : Automatic screen Adjustment Function
If you move suddenly from dark place to a brighter place during the camera operation, the "frame rate" of the camera will change causing the screen to flicker as it may appear.
The flickering happens for approximately 0.5 to 1 second. This has been applied to help prevent the device on future display quality failures.
