After stuck in iOS 16.1 for a while that I think fixed the problem, for unkown reason the touchscreen problem surfacing again. Yes after months with no issue it is not responding. It force me hard restart. That slide to power off, I can't even move it. I want to activate Assistive Touch while not respond, good luck with that. Fortunately after hard reset it respond again but only for few while. After opening some application few hours later it not responding again. After reseting again I decided to activate Assistiive Touch. But I realize delay between touch even after Swipe Gesture on is noticeable. It just don't feel right.
I then finger crossed updated to iOS 16.4.1 hopes the bug fixed. Ya know what, it still there but not too severe I think. It not responding few hours after I play games or some app. But instead restarting, I just sleep button, and wake again, it respond again. It's still annoying though.
