What should I expect to pay to repair my main third camera lense on the 13 pro max, do they have to take the screen off and take the camera out or can “stitch her up compared to open heart surgery”? Long story short this was my gfs little brothers phone I bought when he upgraded the lense was already cracked and when trying to take my case off I pushed my finger clean into it. Now it’s all pushed in it was a decent circular crack all the way around I used to say I don’t really understand how this is holding in but 😂

The glass that covers the back camera on my brand new iPhone 13 crack today while sitting in my pocket. The lens of the camera is fine, this is only the glass cover.

I tried looking up videos to repair this, but every iPhone 13 repair video I found shows a different glass cover. They all have a solid piece of glass that covers the entire back side of the phone with cut outs for the lenses and separate glass where each lens sits. My phone doesn't have this, It's a solid glass piece which you can see in the photo.

Does anyone know where I can buy these parts and have tips and how to fix this myself?

This is a standard iPhone 13.
