Is my front facing camera or my main glass screen cracked?

Hey there,

I had dropped my phone and my screen protector cracked. Keep in mind that it is not a full coverage one, so the front camera and speaker area on top is not covered. Everything is working fine, but I noticed a black line running along the corner of my screen whenever I open my front camera. It’s not a massive hindrance, but it bothers me that I don’t know whether it’s the camera itself or the glass screen! I just want to see if anybody has an idea because I’m not sure if it’s worth the hassle of making my way to the repair shop during this time. I’ve carefully inspected around the area of the front camera, and I didn’t notice any cracks, unless it’s too small to be noticed.

Here is the crack when taking a front facing photo:
