iPad screen freeze, corrupt black screen, auto-rotation problem

I have an empty Unity project with one scene and a sphere bouncing on a cube. Working perfectly and as expected in Unity Editor, 5.6

When testing on iPad, the screen freezes in Landscape mode (see attached images) and starts working if I rotate to Portrait Mode. Also attached are my Project Player and Quality settings.

although I’m not using any scripts

Updating to Unity 5.6.2 seems to have solved this

Yes, you are right. Updating iOS system or app may solve the black screen problem.
