It started doing the keyboard thing quite a bit last night. Got fed up and restored it back down to 18.1.1. It will be a while before I get it set back up how it was before, but so far no keyboard glitches. We'll see about the home screen apps. I think no more betas for me. I think the betas might introduce problems that then aren't necessarily solved by updating to the public release. Whereas maybe staying public to public might keep the issues away.
