hmmm what is flush?
by flush I mean the screen is flat with the dash. One smooth plane. When the latch is pushed in and then pops out, the tablet will be out at an angle. The left side will be further away from the dash, and the right side will remain in place by the hinge.
The latch is activated by the push. granted we "touch" a touch screen, but if you "touch" too hard it would become a "push" and make the left side of the tablet pop out.
I'm sure when the OP gets back to this thread he can confirm or deny if this happens.
