Found the above with a quick Google search.
It's gruesome. I don't know how much more notoriety is needed.. or it's simply beyond the point of fixing.
Yeah. It seems like the new iPads and iPads pro suffer from the same problem , I’ve seen a lot of complainants from people witch the have iPhone X , and iPhone 8 .. my iPhone 7 is superior to my Xs max this is inadmissible ... it seems like It’s a A12 problem... I’m searching every day for a workaround but nothing .. I disabled all of my functions , even 3D Touch and nothing .. I’m literally pissed off...
