A better way to snap between apps on Android
One of my favorite Android shortcuts is the Nougat-introduced ability to snap between apps. Much like Alt-Tab for Windows, you simply double-tap your device's Overview key, and bam: You're zapped back and forth between your two most recently used processes in the blink of an eye.
It's one of Android's most useful hidden features — but with the soon-to-be-released Android P update, it's a whole new ballgame. Thanks to P's new gesture navigation system, the Overview key is no more. So instead of having the handy ol' double-tap-to-snap shortcut, you get a new flick-the-Home-button-to-the-right equivalent.
