Unusable Physics on Mobile (With Video)

Is there a difference on the physics rendering on Mobile devices?
I get very strange physics when i simulate Mobile, or play it on an Android device.

“Enable Projection” doesn’t slove the Problem.

What is the problem here? How can i slove that?

Thanks for any help!
