How to reproduce:
1. Open the attached project "WebCamRotation.zip"
2. Build and run on android device
3. You can tap on the screen so WebCamTexture stops and plays again

Notice four angles on the screen: on frame 0, on frame 1, stabilized angle which is checked during 3 frames and current angle which is called each frame in a while loop.

Result: on frame 0 value is completely random, for example 1620395728, on frame 1 and stabilized angle sometimes returns 0.
