[Unity 5 / Android] How to set Non-fullscreen by Default?

Hello everyone!

I'm developing an Android app and inside of it I use UnityPlayer to show 3d objects. Everything ok, except that UnityPlayer always sets an application to Immersive Mode.

So how can I disable that feature before building Android Project?

P.S. Using Screen.fullScreen = false; doesn't solve the problem. App sets to Immersive Mode while showing Unity 5 logo and then back to non-immersive

P.S.S. UnityPlayer placed inside Fragment
