Malfunctioning touchscreen after a drop
my touchscreen is behaving erratically after I dropped my phone. The top of the screen popped out of the frame (as it did a couple of times before) and now the touchscreen is having a mind of its own. Sometimes it clicks by itself, sometimes it doesn't let me click and it seems to be registering a lot of weird gestures that are straight lines from bottom left of the screen towards top right (look at the attached screenshot).
I've taken it apart, tried reconnecting the 3 screen connectors, took it even further apart, squeezed the cables into the screen, nothing seems to work. At the moment the top of the screen is not glued to the metal case anymore (that's why it popped out of the body a couple of times already), but I don't really think that gluing would help with the problem, as the glass is still well glued to the LCD. I don't want to glue it now, since then it would be harder to replace.
Do you have any suggestions? Something is wrong with the digitizer obviously, but what could it be? I also don't want to buy a replacement screen just to realize that the fault is not actually there.
Any ideas? I really would prefer not to buy a new phone, as I like it a lot and iPhones are really pricey.
Help greatly appreciated! :)
