My 16 pro max touch issues are very inconsistent. When I add a photo to a text message or try and link a website there is a significant lag which I never have experienced with any of my older iphones. The back button in the upper left on many apps requires four or five taps often times. I have always purchased a new iphone since they came out and can honestly say this 16PM is by far the worst Apple experience I have ever had. Still hope an update fixes this.
