I found an Apple bluetooth keyboard and tried it with my tablet today. Every other app I tried it with registered the keyboard fine, specifically backspace. When I tried to type a message to VO Chat, I was unable to backspace with the keyboard, and had to pull up the touch keyboard and tap backspace. I like to MiraCast my tablet to my 40" in the livingroom, and I like being able to use my keyboard and gamepad to play on the bigscreen.

Has anyone else noticed this not being able to backspace bug?

Try changing the keyboard layout in the Android Settings app. There's a bunch of different ones for different keyboard types.
