I've tried different dialers and the same thing happens. Any ideas?
I had the same problem lately with different galaxy model, the problem was with light sensor, the screen was not fixed correctly at the corner of light sensor, so I had to push it down little bit the get the light inside the sensor,
dose the light sensor work correctly with viber for example?,
You could try test your phone light sensor by entering general testing mode by entering *#0*# inside dialer and go to "sensor" to test the light sensor put your finger over the light sensor and see if the screen become green or not if so then your problem is not with the light sensor, check if the touch screen is fixed correctly form all the corners.
