Looks like a lot of people on this string had this issue, and most had it resolved...I had the same issue. I got a Zagg keyboard/case for my Samsung Galaxy Pro 12.2, which I took to Best Buy to see if the Geek Squad could help. They tried a bunch of stuff, and finally told me "it must be broken." So I bought a Logitech universal keyboard (probably like the one you have), thinking the Zagg must be broken. When that didn't work either, I figured the problem must be with my Pro12. Since I've taken pretty good care of the hardware, my hunch was it was a s/w issue. I went back to Best Buy and had their Samsung rep (not Geek Squad - no offense to those guys - they're speciality is prob laptops/desktops) analyze it. The Samsung guy downloaded some Samsung/Google software that he said would be an update, and the issue went away! If you are still struggling with this issue, I recommend doing that. (I returned the Logitech keyboard because I didn't need two BT keyboards, but my guess is that they both would work now.) Hope that helps.
