Keyboard deselecting from default in sammy rom topic

I was experiencing problems in my GT-N7100 where i selected google keyboard or any other keyboard except samsung keyboard but after using it 2 or 3 times the samsung keyboard automatically gets selected and giogle keyboard gets deselected. I am experiencing this problem since 2 weeks or more. If anyone can tell me the fix for the problem that will be appreciated.
