Hi.

I bought my dad an iPhone XS Max a couple of months back from the used market. When typing fast, the screen does not respond very well. I have an iPhone X and the typing and touching response of the XS Max has really been different compared to the X. I attached a video so you guys can see.

Also, the face ID is not working but I did the test where I got in a dark room and pointed a flashlight in the front camera part and enabled auto-brightness. Auto brightness works but not the face ID. software is updated to the latest version of iOS.

Do I need to replace the screen? or are there other diagnoses for the problem? Can I get these (screen response and face id) to work normally again?


I greatly appreciate any help I can get.

I've had old iPhones in the past behave like that with slow typing input. I could easily out type the display. Really aggravating.

In all cases the problem was related to a software update that didn't play nice with the phone. The processor was busy doing something else while typing
