I take back what I said, after working well for three hours I started to see the keyboard lag again. Still not as bad as the first pro max, but definitely not as good as the base iPhone 16. WTF Apple. I will return this again before the two weeks is up if this gets worse. SOME people here attested that they dont have touch screen issues at all with their pro max so I will keep looking until I find one that works as it should. Or maybe I should just settle for the iPhone 16 Plus for my second phone.
