Same here with with iPhone XS, 15.1. Have you found a fix with 15.2?

I was hoping that iOS 15.2 would solve the issue :( Let's hope they give you a definitive solution. Please update us.
What do they mean with "sometimes updates can exacerbate underlying issues"? What a poor answer. So basically the only option is to replace the screen? I have understood that it is not longer possible downgrade to iOS 14. If you find a way to make it, please let me know. Thanks for your updates, Apple is leaving us alone with this problem.
