While being sold bottom quality LCD replacements for my iPhone 5 and subsequently returning them six times I lost one of the screws that holds the LCD shield plate in place. It's the one closest to the home button on the back of the LCD assembly.
Since I continue to have issues with the digitizer / touch screen, I wanted to check whether that screw is somehow integral to the touch capabilities of the screen.
Some issues I'm having:
- No input is registered if I put the phone on a surface and only touch the screen, i.e. without grounding myself by touching the metal case or frame. Plugged in earphones or charge cable works as a substitute to allow input.
- A slightly damp finger makes every scrollview jump around like crazy and makes phantom taps on other parts of the screen.
- Trying to scroll with one finger often results in zooming instead, i.e. pinch gestures.
The LCDs were delivered without any sponges on the plugs of the wires, unlike the official screen assembly. Not sure if that's relevant at all.
