If yes please follow these steps :
1-First downlaod and installe the Google Keyboard App.
2-When you will connect your bluetooth keyboard to your Samsung tablet, and your default is the Google Keyboard you may be told by the system that you have to use the Samsung Keyboard. It may even force this as the default.
Do not fear this is not the case.
3-After connecting your bluetooth keyboard go into Settings > Language and Input From here tap on 'Default', a pop-up will appear with the various keyboards you have installed.
4-set the default keyboard back to 'Google Keyboard' - though you will see your bluetooth keyboard listed, do not worry, it will still work.
5-The Google Keyboard App will now appear, with that all important auto-correct in plain view.
As you type on your bluetooth keyboard the auto-correct will work as before. You can tap on the option you want to use to correct a spelling, or if you have a mouse connected, then you can click on it.
Let me know if you need further help please
