Help Camera Doesn't Work, Displays Blank Screen- Help!

[batness]

HURRAY I found solution, hopefully for you also!
working solution:
- I flashed new ROM and made deletion by Super wipe, after whalaaa works!!

conclusion:
- good news, it is not HW thing, probably superwipe helps, when hard reset is not enough. Note that I had gingerbread, I downgraded to older system first, without superwipe - camera still did not work. Then superwipe and new rom (revolution hd) and works like it did..

hope I helped.

Thanks for the info! Can you give some of us steps on what you did exactly? I am not visual and need written directions for things.

Thank you!

I had this same issue....after searching forums and trying my own fixes (that did not work), I contacted Sprint via chat. The camera on my phone works great now. Here is my chat with the rep:

Followed what was posted by jcolo1 and it worked...removed battery, waited a couple minutes, restarted. All good. Thanks.

I have an HTC EVO 4G and had the same problem described. The camera ap and other aps that used the camera would go to blank black screen. No amount of 'force close' or power down/power up would fix.

Fixed by removing battery for 1 min and reinstalling.

What app did you buy?

When I start the app the camera symbol starts up but then goes to a blank or black screen. The only way out is to hit the home button. Who knows the fix. My phone is updated and has the pre-loaded apps only. Hard restarts and flashing does not seem to work. This problem is all over the internet. Help.

I don't know how this worked but I took the battery out and pressed hard on the camera lens. It had a small snap. Restart. It works now.

Being new, I don't know whether I can write or not.
I have htc desire C. I faced same black-sceen problem.
Got scared, learn the tips & solved.
(1) Put the Power Off (not re-strart)
(2) Remove battery & SD card.
(3) Wait 1 min and start without SD.
(4) Open Camera, no black-screen. Camera is Ok.
(5) Power Off, insert SD, Power On.
(6) Open Camera. Will dictate Photos / videos to Save in SD.
(7) Click Ok to come out or continue.
COMMENTS:-
(1) Probably there had no synchronization between Camera
& SD Card.
(2) Always synchronize all before Power Off.
(3) When everything works except camera, its not a software
problem. Can't be a hardware too.
