At what screen size will the "ow zone" problem become moot because it's impossible to use a phone with one hand? Are we already there with phones like the Galaxy Note 2 and iPhone 6+?

In my opinion Galaxy Note 2 is just too large for using it with one hand. Still, it has a comfort zone where you can reach UI elements with one thumb (either left or right), so maybe the developers should take this into consideration when designing layouts.

If you double-tap the iPhone 6 home button, it moves the content of the screen down so you can reach it with your thumb.

That doesn't sound particularly discoverable. That sounds like a power-user keyboard shortcut for what should be simple functionality.

Most of the touchscreen functions are not discoverable. Pinch-to-zoom, long-press, swiping with multiple fingers, etc. It's very easy to do though, not what I would call a power-user thing. Remember there is only one physical button on the front of the device, and this is one of the things that it does.

Yes, I misuse "power user" to mean "someone who reads the fine manual" or "someone who does a websearch to learn about nice features".

At least for some features like pinch-to-zoom they included very clear examples in the massive ad campaigns. I don't remember seeing this feature in an ad but it wouldn't surprise me. At least it's on this page https://www.apple.com/iphone-6/design/
