The screen on your Galaxy S7 Active is a cutting-edge, yet a fragile piece of technology. There are several mechanisms at work within the Samsung Galaxy S7 Active's screen assembly, and any one of these functions can fail or become damaged. The touch response function (digitizer) can have a limited or a complete lack of touch response. The LCD can suffer from display lines, bleeding, feathering, dead pixels, hot spots, water spots, or can go completely black and not display at all. If your iPhone is experiencing any of these issues, iParamedic's Glass LCD replacement service is what you need. If your screen is cracked but it still responds to touch and has a fully functional display, you may only need to have the glass lens replaced.
