Ghost touches after update

[Samad_ali]

With respect, it is stated that after updating my samsung note 20 ultra I am facing severe issue of "ghost touch" . Please help in this matter.

 I have already reset all settings, network settings and accessibility settings.

So basically if theres any protector on your phone remove it and change the charger cable as well as the plug most often it happens because of the charger or if the the issue remains unsolved go to the nearest service center of Samsung and get your problem solved they I'll reinstall the firmware of it so the problem will be solved
