Rotating the screen messes up keyboard placement and sizing
If you just hold the phone in it's default orientation, everything is fine. But if you rotate the phone to landscape and open the keyboard, the keyboard appears partially over the panel with the main controls (close, home, etc). If you then rotate back to portrait with the keyboard still open the entire keyboard will be placed a bit to the left, appearing outside of the screen on the left side and having a gap where you can see the wallpaper on the right side.
