Touchscreen not working after display change
After dropping my Nexus 4 and breaking the front glas, the touch screen did not work anymore. I decided to change the full display unit (digitizer + LCD). I have now replaced the display unit with a new one and connected everything as it was before. Turning on the phone worked instantly and the new LCD shows a flawless starting screen. However, the touch functionality does not work at all. So now I'm wondering if I made a mistake in reassembling the phone or if the new display unit is defective. Is there anything I might have missed? Or is there a way to test if the problem lies with the display unit or the rest of the phone?
