Thanks for your answer(s).
GetTilt never worked for me.
Currently i found i way for up and down. (still working on left and right)
I use (as blueprint):
GetMotionInputState → take Gravity → Break Vector → take Z Value and then i do rad2degree conversion → some math to “smooth” the value → Make Rot → use Pitch pin → Set Actor Rotation (i my case a pawn with camera)
This works good when deployed on an android phone.(I can look up and down)
I want to know if this is the right way of doing such thing.
