Windows Phone 8 (or even 10) with wordflow was the best prediction/autocorrect experience I've used. I sometimes want to fling my iPhone at a wall in frustration. My only experience with android is a low-powered phone and Swype on that was quite bad, but maybe it's better on high-end Androids ? Or is there a better keyboard over stock and swype ?
