LG-H918, been a great phone. Not rooted, all original.

As of today (first I noticed) when you touch the recent apps square, the various apps appear, and you can scroll through them. Each time I attempt to select whichever app, the phone blanks very quickly and returns to the home screen.

I can clear the apps in the recent apps screen by swiping and using the x.

If I try split screen on apps that are able to use it, the first app appears at the top, and when I try a second, the second blanks and the home screen appears on the bottom half. I then can expand the upper app to fill in the whole screen.

I've repeatedly restarted the phone, and also shut down and removed the battery. No effect.

Is there a setting or something I may have done to cause this?
