Enable screen auto-rotate for specific applications but not globally? So I'd like to enable screen auto-rotation for YouTube and Chrome, but not for other anything else. How do I do this?

I use a Galaxy S5.
Have you tried a 3rd-party app like Smart Rotator?


  Are you tired of switching auto-rotate setting back and forth? This
  tool can help you auto switching it.
  
  You can set auto-rorate/portrait/landscape setting for each app, when
  you open those apps, it will help you set screen orientation to auto,
  portrait, landscape automatically.
