Issues with touch sensitivity on iOS 15 update?

Has anyone else experienced the glitch with the power button not working or responding with the iOS 15 update for anything involving the iPhone 12 Pro? I had to flash reset my phone, and since then it’s been having issues with touch sensitivity in multiple apps and the only workaround is to refresh the page. I would like to think my phone is kept in relatively excellent condition and hasn’t been dropped or suffered any type of damage or anything like that.
