I have a year (2 in EU) to replace it so I won't rush and risk getting a worse one. I hope the touch issues will be fixed with an update and if not, well, then I'll replace it.
I remember after the premiere of 15 pro max some people had burn in screens after a short time of use and others had good ones. Also then people were sure that it was a hardware problem and some exchanged for new ones that did not have this problem. As you well know, it turned out that the software was to blame and the update solved the problem and the screen burns disappeared as if they had never been there before.
1/2 years is warranty and Apple can attempt to repair your phone instead of giving you a new one.
If you want a new one you better act within 14 days.
