iPhone 7 Plus camera not working

My iPhone 7plus camera stopped working soon after I updated to ios 11.4 😢

At first my camera was just freezing and showing green glitches.

That soon stopped as well and I just got a black screen whenever I opened the camera app.

Anyway, I updated to ios 11.4.1 hoping it would work but I still have just a black screen. The flashlight stopped working as well and the camera doesn't work on any other apps like Snapchat or Instagram either.

I've tried hard reset, restarting and everything I could possibly do but nothing worked. I even reset all my settings but it has made no difference.
