To exit split screen, simply swipe the center black bar all the way up or down.
Thanks for helping.
That works pretty well.
I was hoping for a permanent solution. Is there a way to disable it completely, so it cannot happen by accident.
I think the thing that bothers me most is Google Maps, sometimes when I am driving the phone will get jostled in its holder and the map will shrink to an icon size.
In Oregon, in a holder attached to the dash, it is legal to touch your phone but it is still a pain and in traffic it can be quite dangerous. Out of dash, you can only use one swipe or its a violation.
It just seems that I am always adjusting the Google Maps icon so that it will take up the whole screen. If I use bluetooth to answer a call, it shrinks up and I have to adjust it.
Maybe the question I should have asked was "How do I stop Google Maps from becoming a tiny icon"
When I say "Thanks" but then launch into additional problems it makes me sound a little ungrateful. I hope you don't take it that way. I am very appreciative that you helped.
Edit:
and hope that you will also tell me how to stop the Google Map icon problem.
(one of the biggest problems with boards is we cannot read each others body language, so we can't tell when someone is appreciative, like me, but wishes he would have asked the right question)
