Simple question, why root the tablet? Does not the TB game run a standard tablet?
The game runs fine but when I find bugs I cannot send the savefiles to the TBs to debug them. Android calls this a security feature. It has also let me remove Bixby from the tablet and other things Samsung and Google have made impossible to delete without being rooted.
