[Android] Player Loop in Profiler is not steady when empty Scene is open in Player

-

Reproduction steps:
1. Open the attached project “PlayerLoopNotSmoothProject”
2. Select Android in Build Settings
3. Make sure "Development Build" is enabled in Build Settings
4. Enable Autoconnect Profiler
5. Build and Run on an Android device
6. Inspect PlayerLoop in the Profiler

Expected result: The PlayerLoop in the Profiler should be smooth/flat at 16.67 ms
Actual result: The PlayerLoop as shown in the Profiler is very jaggy

Reproducible with: 2020.3.48f1, 2021.3.25f1, 2022.2.18f1, 2023.1.0b15, 2023.2.0a13

Reproducible with these devices:
Samsung Galaxy S10 (Mali-G76 MP12)
Huawei P30 Lite (MAR-LX1A) (Chip: Kirin 710, Gpu: Mali-G51, Android 10)
Samsung Galaxy S6 edge+ (SM-G928F), Android 7.0, CPU: Exynos 7 Octa 7420, GPU: Mali-T760
Samsung Galaxy S9 (SM-G960F), CPU: Exynos 9 Series 9810, GPU: Mali-G72, OS: 10.0.0

  1. Resolution Note:

    After testing, we can confirm that the fluctuations seen around the time taken for the PlayerLoop and the median loop time are within the expected range. There are no abnormalities when checking CPU usage or logs.

    The small variations seen per loop are normal and can be caused by many factors, such as time taken by the app when migrating between CPU cores or performance change due to CPU frequency scaling, etc.

    Ensure the "Optimize Frame Pacing" setting is ticked if it isn't yet, as this option can reduce the fluctuation on Android. Closing as no fix is needed.
