Disable Split-Screen/Multi-Window for apps Forgive me if this is a duplicate post as I couldn't find a solution in post history.

My question is concerning Split-screen/multi-screen functionality in Android Nougat. Is there a way to disable app split screen functionality? My device is a rooted Motorolla Nexus 6 with Android 7.0. I was wondering if there was an adb command or a line I can add to the build.prop file to disable multi-window in the system.

If it is easier, is there a way to simply change what occurs when the recent app button is held?

You can tweak the Overview (Recent) button for long-press event using GravityBox [N]. GravityBox requires a comapatible Xposed Framework. 

In GravityBox module, go to Navigation keys actions &rarr; scroll to Recents key &rarr; tap Long-press action &rarr; choose an appropriate action. 

From then on, long-pressing the Overview button would not show spit-screen mode. 

Tested on Nexus 6 running stock Android 7.1.1.
