Hi all, hope you can help. I sat on my remote the other day, somehow split the youtube app to the left side of the screen, like you can with an android phone.

The thing is I don't know how I did it. At one point I went to home selected a different app, it opened on the right. Had to reset the TV to restore fill screen.

Does anyone know how I did his? My Philips TV doesn't support multiview apparently, but if I can do Android split screen that'd be great.
