Hopefully they do fix it ! This stuttering and jittery scrolling did not happen on my iPhone 1,2,3,4,5 and 6 and I’m pretty sure that’s why a lot of us are noticing it now. We should not have to put up with this on new devices. A smooth UI was the main reason a kept with IPhone but if this stutter is normal across all new devices, then this is a poor move from apple. I choose not to ignore it because it is a feature that I have never seen before and dam right Annoying especially when scrolling, playing videos and games.
