Yes! It is a hardware defect. Fixed my screen and everything works as it should. If you have your screen repaired by a non authorised repairer, make sure you test both cameras, speaker, light / proximity sensor and hardware buttons. In my case, the repairer explained that one of my screen connector pins was damaged which ultimately lead to problems associated with hardware that's on surface (buttons, camera, speaker/s, sensor/s.
