Android device shows a ball that doesnt exist!

Hey, guys!

I am a bit new to UE4.
I am having a weird issue when i try to deploy to my tablete. A LGV500.

The project is deployed with succes, but on the tablet, i can see a sphere that is not on the editor.
The image below (wich is upside down), show what i mean.

Anyone know what is this? I tried to create another scene, copy and paste the contente, but the problem continues.

I thank you in advance!
Good night.

Rodrigo
