iPhone 18 pro max screen response

Nope. Touch on both our iPhone 18 Pro and 18 Pro Max is just fine. Have you read this and tried any of the options --> Adjust how iPhone responds to your touch - Apple Support

I understand what you are saying. Those who don’t simply hadn’t experienced it to chime in with anything that is supportive. I’ll describe my experiences through these 2 months of use. (1) there are numerous instances where the screen totally hangs and the only resolution at the time is to force restart. This did not happen before with my 512Gb IP12PM (previous phone)

(2) what happens more often is that the screen suddenly do not respond to left/ right swipe motion but is able respond to up/down swipe motion. Opening control and swiping up for the app switcher is fine but I wont be able to switch apps due to poor/ nil response for L/R swipe. This includes being unable to swipe right to turn off the phone or even swipe right for SOS at the power off screen. However, when I tap and hold an app icon, I can freely move the icon anywhere including left and right movements. I have videos (taken beside me by someone else) to show these.

It’s not very responsive.Takes a bit to just close a window.Not that happy with it.The 17 pro was much better.Wish I had not upgraded
