S23 ultra not responding to touch with UI 6.1 Update

[Gemini0907]

I have replaced my screen wuth a non OEM screen and I am having issues with touch. only the S pen is responsive to touch.

Should I downgrade system software?

Non OEM screen might be a possible reason. I think you should visit the technician who replaced your screen.

Yes, I read about this issue I suggested, like my brother Zammi.
