Device View for the mobile recorder is displaying much smaller than the allotted window

Hey there team, I have been searching through this forum and have not found an answer for this. Basically what is happening is the app displayed in the device view window (when I am using the mobile recorder) is only filling in 1/4th of the window. I would like for it to at least fill out the entire device view window as this will make selecting objects much easier. Any solutions to this? I am using a Samsung Galaxy S8.

Please update to v6.3.3.

Thanks
