A few days ago the left side of my iPone 6S became unresponsive on the left side of my screen, I believe it has something to do with the fact that earlier that day I dropped it. I’ve tried rebooting it several times but nothing is working; I think some of the internal wiring got messed up or something. I have no idea how to fix it and any help is appreciated. Thank you
The screen is most likely damaged from the drop. The first thing to do to diagnose your phone is to open it up and check that the connections are good. If that doesn’t help, then try a good quality (or known-good) replacement screen. You can follow this guide.
