Why does my screen keep minimalism when I am watching YouTube or some sort of video on my screen?

[Android Central Question]

After about 15 to 30 seconds my screen will go from full size to minimal small size in the corner whenever I am watching a YouTube video or a movie or anything that has a video.

Welcome to Android Central! Which phone? Could it be that you're accidentally tapping the Home button?
