Hello!
I’m using Unity 2019.2.21f and I have problems with some mobile devices with android +8.0. After 1-2 minutes my game has big fps drop that causes whole app to freeze. The performance isn’t a problem as I checked in a profiler and etc. additionally on older devices (with lower Android version) app runs incomparably smoother and without any crashes.
The packages that I have are Advertisement and LWRP. I tried to enable and disable any experimental functions and nothing. I don’t know what may cause the problem. There are no any script issues like infinite loops or optimization mistakes.
Ps. The game’s target api level is 30, and I use newest SDK tools.
