Every Android device I’ve ever had since the early days lagged like crazy. I got my first iPhone recently and it’s smooth as butter. I was a fool for sticking with Android for so long.
For Android most of the lag (IME) is artificial. To disable it, enable the Developer Options panel, and set "Window animation scale", "Transition animation scale", and "Animator duration scale" to off (or minimum value if you still want some animation). Suddenly it's much more responsive!
Totally shit design. And could still have lower input lag. But instead of reducing it they added slow animations to try to hide it, which makes it take even longer!
