As, smart phones are originally fitted with corning gorilla or dragon trail glass displays, any lower grade glass display used by the repair company, will harm the overall performance of your cell phone. It is often seen that, as compared to original screens, the touch sensitivity of the inferior and low quality screens, is poor and sometimes unresponsive too. Hence, as far as possible, always insist on getting your screen replaced either by an original or similar quality screen for your damaged phone.
