I have an iPhone 6 plus and find the design of “Reachability” perplexing. When you double tap the home button – the entire screen shifts down making things that were not reachable before, reachable (one handed). But the fact that the keyboard shifts down as well and is now hidden, it seems 50% useless to me. Shouldn’t reachability have a “Right Handed” and ‘Left Handed” setting and when you double tap your home button, the whole screen reduces in size to about the size of an iPhone 4 or 5 and moves down to the right hand corner for right handed folks and left hand corner for lefties? What do you think?
