How to bring the Note 8's App Pair split-screen shortcuts to any Android phone
Samsung popularized the split-screen multitasking on Android with its popular Multi-window mode before Google went out and appropriated the feature, integrating it into stock Android builds with the Nougat update. Debuting on the Note series, Multi-window was in its exact place on these big-screen phones with S Pen stylus that could resize the windows and pinpoint actions to take with precision better than what your fat fingers were capable of.

That's a pretty svelte idea, but, unfortunately, it's only available on the Note 8, so how can you replicate it on your own Android? Here's the gist, though it works only on phones with Nougat and above, for obvious reasons:
1. Download and install the Split-Screen Creator ($0.99) app from Google Play;
2. Open it, select the shortcut, and choose which two apps you want to open in split-screen mode at once;
3. Tap on the resulting shortcut to launch the two apps you chose, and have them immediately available in windowed mode.
