Hello, so I dropped my nexus 4 and completely shattered the screen, with the screen being shattered the touch was unresponsive as well. I watched a video on how to replace the screen, and did everything. The new screen that I bought on ebay works great, the only issue I have is the touch is still unresponsive on my new screen. I took everything apart again and re-checked all of my connections and they all seem good. What could be causing this?
