Go to settings-applications-all applications. choose the camera app and clear the data on it.
Also, gently press on the camera lens and see if that helps. I've seen issues on other forums where the camera came unhinged slightly.

 

Did you do a battery pull?

 

Sorry, I don't know what to tell you then. Sounds more serious than the troubleshooting you have already done.

 

When you say a hard reset, do you mean a factory reset? Did you wipe the phone clean and start from scratch?

Also are you rooted, or stock?

 

take battery cover off push hard down on camera, then restart evo this may work, you dropped it and evo's have pin camera

 

I had the very same problem. I did just as you did (pressing hard on the lens) and the camera now works!

I have dropped the phone in the past (who hasn't?). I'm betting this could easily fix this problem for many with the same issue. Thanks very much for sharing!

 

If you had read my original reply you would have had it fixed earlier

 

Thanks tube517, jkogas, daxlw, yama143.... I took the battery out (don't know if that was necessary or not, but I did it anyway). Pushed on the camera lens -- didn't have to push hard at all -- and heard / felt the slight "snap" and immediately knew it was gonna work. And it did. So, yeah, thanks again!

 

I pushed around the camera gently. After a few seconds it clicked in. I didnt even have to take it apart. It happens when you drop it. Same fix as taking it apart but with less chance of messing up something else. I did not have a camera for a month... All i did was this quick fix and now it works like a charm. Good luck!

 

Good advice all around. You wouldn

 

ThankYou all for the tips. Even though my reply is old the info is still valid. I did the taking cover & battery out & pressing hard on the camera , I did not hear or feel a snap but it worked, so ThankYou to all for their input.
