iPhone 11 pro ghost touch issue after updating to IOS 14.7

I have tried many ways i found on the internet- clearing settings, restarting the phone or force restarting the phone.. though it seems not solving the (1) insensitive screen (e.g. cannot sense when typing passcode) (2) glitching and (3) ghost touch issues

Even worse, the issues are getting more and more serious. I have been an Apple fan for years and never thought of switching to other brands. :(
