I know next to nothing of Samsung phones, except they are, usually, blatant copies of the iPhone.
The new iPad Pro models use a new liquid retina display technology.
The same type of liquid retina screen technology used in the iPhone Xs and Xs Max, but the smaller screen sizes are not bothered by any phone screen protectors.
The much larger liquid retina screens used in the new iPad Pros are the ones that are problematic.
To compound this issue, there is a growing minority ( over 800 users, now ) of users of all three years of iPad Pro models experiencing intermittent unresponsive touch screen issues as a result of some issue/glitch/bug in iOS 12.
So, there are two issues going on with touch screen issues specifically with iPad Pro models.
