Nexus 4 touchscreen not working after replacement

I took my phone out of my back pocket and it was cracked the other day so I replaced the screen myself. It displays fine but is unresponsive to touch. I can't think of anything I did wrong. There was some grey cloth underneath the screen I didn't put back and I did a lazy job on taping the screen back since it was late at night. maybe that's the problem? The display sits just fine though

Re: Nexus 4 touchscreen not working after replacement

It could be mnany things. You could have pinched a wire, causing a short and frying an output on the motherboard. You could have a connector not fully locked in. You could have pinched a wire and cut it. You could have something on the screen grounding because you didn't replace the insulator. You could have bought a screen with a defective digitizer.

That's why paying a shop to fix your phone is usually the cheapest option.
