On my galaxy note, I use Ultimate Rotation Control by FaMe IT. When I am low on power and still want to read (or do anything else, really), it can sometimes be awkward having the power cord on the bottom. Also, with some games, the home button can get in the way while in portrait mode. This program makes things much easier.
As to your particular problem, I'm sorry I don't have a solution for you.
