How do I lock iPhone 5 in landscape mode? How do I lock iPhone 5 in landscape mode? I see how to lock it in portrait mode, and I've tried locking it in landscape mode using the assistive touch feature, but that isn't working for me.
Apparently you can!

If you want to try this out for yourself, here is the navigation to get to the setting:


Enabling AssistiveTouch: 
Settings App>General>Scroll Down to Accessibility>Scroll Down to AssistiveTouch '
Toggle on AssistiveTouch.


Switching to Landscape:


Lock the device in portrait mode
Press Floating Square>Device>Rotate Screen>Left/Right
