Android P may take some time before reaching your device, so in the meantime you may be able to take advantage of some of its most desirable features by installing third-party applications or finding workarounds.
Example: Android P’s new volume menu moves controls from the top left of the screen to the right side for easier one-handed use. To bring this feature back onto older Android devices, download and enable XDA Labs’ free Volume Menu app with all required permissions.
Android P’s system for sensing when your phone has been rotated features an icon in the corner, making it easy to tap when changing orientation. To add this to older devices, download and install XDA Lab’s free Rotate Screen app – once done simply launch it to select your preferred rotation mode!
