Android Build working in Bluestacks but not on the Phone

Hi everyone,

My build is working fine in Editor and on PC. The Android build is working fine in Bluestacks but when I have downloaded and installed the game on Android Galaxy S4.

It will load unity splash screen and then my main menu to select a scene.
When I select the scene, some of the items are visible and rest is all Black and buttons don’t seem to have any kind of control or interactivity.

I have attached two screenshots with this thread, please. and thanks for your help.

I think I have found the Error. It’s in my UICanvas. I used a Fader and that seems to be an issue. I hope it will help someone in future. If you see the black screen on loading of a scene. Check your UICamera / UI Items as well.
