Rolling Ball bug on mobile

Hi everybody !

I have an issue with my rolling ball game, when i play on my mobile (One Plus 3t), the ball does smalls “jumps” and I don’t understand why. I have already done a FPS meter and it indicates 60fps (at the beginning of the video there is probably a fps drop because of recording). When I play via Unreal there is no problem but when I launch on my mobile there is.

I set velocity with “Set Linear velocity”, i know this is not the better way but it’s why i need to have the comportement i want. I’ve already tried with “Add force” or “Add torque” et the result is the same (smalls jumps).

I have no idea what cause that, does anyone have an idea of ​​what’s wrong?

Here is a video of the issue :

EDIT : I succeeded to delete these smalls jumps by setting the “smoothed frame rate range” in project setting. I set min = 29 et max =31. I can’t explain why that’s work but i hope it can help you to find the origin of this issue.
