Android 9 Pie vs Android 8.0 Oreo Walkthrough: What’s New

Rotation Tool (and Lock)

Landscape or Portrait mode, known as Rotation or orientation controls, are a little different on Android 9 too. 

Most users have the orientation locked in portrait mode, and only things like games or Netflix and YouTube can turn the screen sideways, in landscape mode. This is by design. 

However, sometimes you want to quickly allow an app into landscape mode but don't want to fumble through the settings menu. Now, when you turn the phone sideways if it notices content trying to turn, you'll see a little "rotation" icon on the bottom left side of the screen. Click that to instantly allow rotation or orientation changes, on the fly. You'll need to tap it again to revert back to normal portrait mode.
