On physical keyboards Qwerty isn't very good, but it turns out that touch screen devices have different keyboard layout needs. Since autocorrect finds potential mistypes by looking at adjacent keys to the one tapped, clustering high frequency keys all together isn't a good idea. The two most popular alternative keyboard layouts (Colemak and Dvorak) do this clustering to try to minimize the distance your fingers need to travel. Typing on a touch screen and on a physical keyboard are so different (at least for smaller devices like phones) that you can use an alternative layout on your computer and stick with Qwerty on your touch device.
