If you did the new update for street view that's whats is disabled your camera. Uninstall back to the factory app on it and then restart your phone.

 under trusted credentials I disabled four that said camerfirma . And boom camera works.

My phones camera says it's disabled but, I went under the settings and tried to disable then Enable the application, still nothing. Also (if you don't mind) my phone was given to me by my mother, she told me that it had been dropped in the toilet but still worked. When I got the phone it turned on for a moment until I turned it off so I wouldn't run the battery down when it shut all the way down. I thought maybe it was just a fluke but when I tried to turn it back on it wouldn't, I tried it a few hours later and it turned on but did the same thing. Do you know what I could do to fix it?

Please help i tried reseting and rebooting nothing worked help :(

OH Boy.....I did all the above and all the above in many forums..got Samsung troubleshoot over a chat factory reset 3 times...safe mode...so the only thing that I could figure out was under settings...security....clear all certificates was greyed out so I could not do that...then under security ..trusted credentials..display all certificates I find about 100 certificates and have to disable each one...then I did the hold volumn button with power button together and get the black screen to restart the phone...after 2 weeks and hours of frustration I felt like I had my first baby..cause my camera and my flash was WORKING! Oh joy and bliss

1.go to hard reset menu (Power off phone, HOLD volume up and power buttons until android screen pops up, quickly release finger from power button and hold it once again, HOLD until a new screen pops up) 2. Choose wipe cache data 3. Choose reboot after it's done!

How to fix this

I just purchased this phone yesterday and when I tried to use the camera it said that it was disabled or that another app. was using it. Also, the flashlight isn't working either.

Yes I did but I just uninstalled it n its still causing the error message...ugh this so pissing me off

Hi guys! Did you install anything before that started happening?

Same here! What the EFF?
