Samsung keyboard Neau"
Only down side the keyboard is white on black (dark format)
But it work with spell checker. Now.

This solution works perfectly. I had exactly the same problem. The new keyboard is better than the old one and it is not white on black.
Guys, please note that to get the keyboard button on the bottom right, you need to select "show keyboard button" in the On-screen keyboard configuration options.
How bizarre!! Changing keyboards worked for me too. I have been fighting this for weeks and it was killing me. Does anyone know what really caused the problem or is this just the android/samsung way?
