Fun, but not fair

Ive been playing Backgammon Guru Pro (on a "strong" opponent setting) for a few weeks now on my iPhone 5. I do enjoy it most of the time, but it really bothers me sometimes that the dice rolls are not random. There is no way that the computer can roll doubles 4 times more often than me. 8 times out of 10, after asking me to double the computer will either roll doubles, or will get exactly the combination that can both knock off my piece and set up a great blockade. Just so you know, Im a 55 year old science teacher with a Ph.D. Ive been playing backgammon for decades, and Ive also had multiple graduate level statistics classes, so Im pretty familiar with the way dice rolls should work if they are truly random.
Also, it sometimes takes me several tries to get my checkers to move. If you could widen the acceptable "touch" area after a piece has been chosen that would be nice. Theres only 2 places a given checker can go, so youve got at least half the screen to work with--theres no reason you should have to touch right at the points tips.
