For me the stealth works but only when I use the boost, right after the boost is finished the image freezes again (using the boost again after waiting for its cooling down will "unfreeze" the game, repeating this again and again til the stealth is finished will completely unfreeze the game and then you can play normally)

Don't know if the achievement works with that, didn't tried enough

Btw I have an ipad and uses the shadow yin ninja and polytron boost with a rhino.
