I dropped my iPhone 6, there is no cosmetic damage to the phone, it is still in perfect condition, the screen is also fine and everything is visible with no lines or pixels or anything, but for some reason, the bottom half of the touchscreen is now unresponsive. I have tried a hard reset and it didn't work, and no I can no longer unlock my phone because the 4,5,6,7,8,9,0 keys are no longer responsive. The top half of the screen is still fully responsive. This means I can't plug my phone into my iTunes to attempt a restore because the phone has to be unlocked for it to connect. I am so done with this, somebody please offer any advice!!
