XS MAX TOUCHSCREEN ISSUE

I have an iPhone XS Max and I’ve just updated the phone to iOS 14.

Areas of the screen becomes unresponsive many times during the day. Locking the screen and unlocking it again seems to temporarily fix the issue. Removed the screen protector, and restarting the phone doesn’t seem to fix the issue. Updated to iOS 14.3 recently and the issue remains to emerge every once in a while during the day making it difficult to operate, navigate and especially type on the phone.
