There’s a lot of really bad quality screens on eBay and Amazon; it’s really hit or miss. If you want good quality screens, look at iFixit or other reputable suppliers. They’re more expensive but you get what you pay for ;>). As for your existing screen, take a look at this [guide|56283|guide] (if you haven’t already) to insure you have mounted everything properly. That “metal block” below the camera is circuitry, don’t go and apply pressure to that to move it, otherwise you will destroy the screen.
