Why does my forward facing camera no longer fill up the whole screen?

[AC Question]

My forward facing camera's dimensions have shrunk into a little bitty box on the screen. I have found nothing in the cameras settings or in the help section in how to fix this.... Help? Me? Please??
Thank you,
Jami C.

Welcome to Android Central! Which phone? Are you accessing the front-facing camera using the Camera app, or are you within some other app (like a chat app)?
