why does my camera not work?

[AC Question]

I have a samsung s3. I dropped it one day and I don't remember if the camera stopped working then, but everytime I open my camera it says "camera failed". We've brought it to a Phone shop to fix it but it just doesn't work. It also doesn't show apps like snapchat and pokemon go in the playstore. My front camera does work though, but only if I open it via instagram. I hope someone can help by telling me what to do to fix my camera.

Welcome to Android Central! Does it work in Safe Mode? How to boot the Galaxy S3 into Safe mode?. If not, then the camera module or one of its connections is probably damaged. You'd have to get it replaced.
