When I try to use my tablet while lying down, it constantly shifts from landscape to portrait and I'd like it to stop doing that. I figure that disabling Smart Screen is the way to go, but I can't find where to do so.
I hit the wrong button and set it to be the default for a text file, but the text file is too big for it. I'd like to unset the default so I can use some app that will work, but I can't find DB Text Editor in Application Manager to do so.
