Hi, I am having the same problem with an iOS build:

http://answers.unity3d.com/questions/1343764/magenta-screen-on-game-start-on-ios-port-of-a-game.html

Usually, magenta (pink) means there is a texture/shader/GPU issue but I have never encounter a magenta screen.

If someone have any information please let me know.

I found the problem. It was in Canvas. I had to reset graphics settings and it all started to work.
