Antwoord op "Touchscreen on the Nokia Lumia 920 does not function"The mainboard is flimsy and pretty durable. However, after installing my nth 920 screen I accidentally bent the board too much. Didn't realize it was that big of a deal until it didn't respond to touch. I tested the screen in another phone and it works fine. I can also get the screen to work if I dont put the case on the phone and bend the mainboard in the right way.
