This is literally the only annoyance I have with my Note 2. It's rare, but it does happen (usually in the browser). So thank you for this workaround! I'll have to give it a try the next time it happens.Screen rotation is bugged as hell on my Note 2. Gets stuck pretty often. I googled it and found a fix that seems to work - do anything that brings up the keyboard and it'll start working again.
It's pretty annoying though, hope they sort this in a future update.
