White space sending me back a screen

[ShanP]

When testing the app on my phone, everytime I click a blank (white) space, I am sent back a screen. This does not happen when I am running the play button in the editor. Screenshots are shown above for the meaning of the blank space (circled red).

That is a strange behaviour. What are those blank spaces exactly? How are they created? Is there an invisible rectangle? 

Check if any objects have OnSelect function back() (this would explain it going back a screen).

The OnSelect was the issue. I had a navigate function sending me back.
