Android build not displaying correctly? (answered)

I have a great game that I have made but when I build it to my SONY XPERIA MIRO, it doesn’t display properly. Part of the skybox (that is a mobile skybox) renders partly black and the screen is all pink and purple. Also, when I move my character around, it lags and just goes all strange on the screen. And to add to that, when ever a scene changes, it shows a the previous scene behind it.

Has anyone got any ideas why this is happening, all my textures and materials are on mobile and i haven’t got any shaders on. I am using the latest version of Unity on a macBook. Does it have anything to do with my phone?

HELP because literally my game is unplayable and so sucks…

Fixed it! Thankyou. It was my graphics on the phone that were not good enough.
