Reproduction steps:
1. Open the attached project;
2. Build the scene "main" on Android platform with enabled Development Build option;
3. Open the built program on device;
4. Open Profiler window and attach the device;

Actual result: Graphics.PresentAndSync time is around 50-60 ms. Profiler performance is 15 FPS.
Expected result: Graphics.PresentAndSync time should be around 30-40 ms. Profiler performance should be 30 FPS (performances.jpg).

Note: The issue happens only with "Mali" GPU, but does not happen with "Adreno", "NVIDIA"and "PowerVR" GPU.
