How do I get horizonal views on the iPhone 6 plus and better keyboard?

Make sure your rotate is not locked.

Pull up control centre, by swiping from the Home button to the top.

The top right button toggle ON/OFF.

That didn't do it. Any other suggestions?

Not all apps have a special horizontal view. What apps are you talking about?

In order to use these features, the display zoom must be set to standard view

Thanks to Alonso at Apple support for this tip.

I had the same problem. make sure your display zoom is standard
