Help LG G3 Camera not working

[TheEms2]

SO I recently got a T-Mobile unlocked LG G3 and have it with a Cricket SIM card, but the camera hasn't worked since the purchase, I've tried all of the normal fixes like clearing the camera cache, trying a third party camera app, and even the factory reset, but none have worked. When I open the app it just shows a dark screen with the one back button in the bottom, and it doesn't do anything else.

A factory reset should have fixed it.Sorry your camera won't work.
Then it looks like you purchased a phone without the camera,If purchased through a store then return it.If you purchased it like on Craigslist.I am sorry to say you are SOL.

You can replace the camera module, it only costs about $20.
