Gear VR freezing - 40 fps

Hi everybody,
i’m trying to make an application for gear vr. Idea is simple: it’s something like excursion, you are on planet, and when press start, planet starts to rotate and you are passing through a village.
I’m using low poly models and i don’t have many objects on scene.
So my problem is that when i run app on my Samsung S6, i have 40-45 fps but my view is freezing. I mean that when i press start planet is rotating perfect, but when i start to move camera it start freezes (there is still 40 fps).
Can somebody help me, or give an advice ?

P.S. i’m working in UE 4.11
