Android game stutters (ruckelt) on splash screen and in game

Hello, my problem is that my unity android game stutters in build. When I install it on a device, every 10-12 time it has this problem. The splash screen is after one second for one second black and then it goes on and goes to menu. In menu is no problem, but after I start my game it is like every 2 seconds it starts to stop and go forward in level. It’s like something is cutted out. I use Unity 2017.2.1f1 (64-bit). But I tried it with other versions and I get this error, too. It occurs to 10% or something like that. So often I thought I solved it, but it occurs again.
Thanks for help!

Been working tirelessly and pulling what’s left of my hair out trying to solve this problem. Did you ever figure it out @scury547 ?
