iPhone 12 mini touch screen won't respond after iOS update
After my 14.7.1 update overnight, my touchscreen is unresponsive. I had kept up with all updates and never had touchscreen problems until after this update. Have only had phone 6 weeks. Cannot swipe up to go through follow up update (so stuck on seeing hello in all languages); cannot turn off alarm. Cannot swipe right to turn off phone for restart or enter passcode (passcode screen is gray). My computer does not recognize phone when plugged in, so I cannot even restore to factory settings. Took off screen protector and case, plugs and ports work fine, etc. I really think a software issue but am stuck on how to restart, redo update or restore if not recognized by computer and with touchscreen not working.
