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
5. Wait for 2-5 sec

Expected result: Frame rate is stable around 60 FPS
Actual result: Frame rate drops to 40-50 FPS (user mentioned frame rate drop from 45-40 and lower on Amazone Fire HD 8 (12th generation))

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
