[Android] Frame rate drops to 40-50 FPS on some Android devices with spikes in the Profile for "PostLateUpdate.FinishFrameRendering"
How to reproduce:
1. Open the "IN_67380" project
2. In the Build Settings "Run Device" dropdown, select the desired device
3. Press Build And Run
4. Observe the FPS displayed in the Player

Expected result: Frame rate is stable around 60 FPS

Notes:
- Reproducible with both Vulkan and OpenGLES Graphics API
- User mentioned that opening up the app/task switcher and then going back to the Player causes the frame rate to return to a steady 60 FPS (possibly depending on the device but this temporary fix worked only for a few seconds on tested Htc 10 device)
- User mentioned "Creating an AdMob banner ad view in the game seems to resolve the GPU issues and frame rate dropping"
- Device Amazon Fire HD 8 (2017) behaves the opposite: on this device the frame rate varies between 60 and 70 FPS (increases)
- User mentioned spikes in the Profiler “PostLateUpdate.FinishFrameRendering/Gfx.WaitForPresentOnGfxThread/Semaphore.WaitForSignal“ but I couldn’t see any spikes specifically caused by “Semaphore.WaitForSignal“ but higher usage increase was observed on “PostLateUpdate.FinishFrameRendering“ when frame rate dropped
- Not reproducible on the Windows Standalone Platform
