I hate split screen. I am constantly setting it off unintentionally. I have tried to find the setting to control or disable this, but I haven't found it yet. Is there a way to disable it?
I'm also interested in this. Does someone know how to turn it off? Or know an app that can utilize this feature? I always get the message that the app doesn't support it...
There are some apps in the Play store to either disable the multi-screen feature, or add a toggle to the drop-down menu from the top of the screen, or both. Search for "multiscreen disabler" and try out different ones until you find one that works well on your phone. I did not want them interfering with each other, so I installed one, tried it, uninstalled it, and tried the next one, etc.
