My camera doesnt work,i tried to take a photo and irt froze so i exited the camera.since then,everytime i try to use the camera,it says the camera is unavailable. what the hell do i do?

Double Click the home button, and kill the app. wait a few minutes and try again.
if that doesnt work, try turning the phone off for a few minutes.
If this doesnt work, check to see if your phone has enough space in your usage settings under Genral in settings.
And if none of these work, your camera may be broken. Bring it to an apple store to see.

did the photo managed to get stored in the memory card?
can try with another memory card?

sounds like an issue with the sd card itself. you may have to reformat it. or CHECK the sd card make sure its not stuckin the the lock position. let me know if that helps.

Try inserting a fully charged battery.
If that doesn't work; you may need a new battery.
Write back if none of these work.

Try these procedures.

try to upload all of your photo in your computer, then after copying your photo try to reformat your memory card using your camera,

reset camera, take out battery, try manual repair

First of all with a Casio camera Casio will only guarantee the camera to work with Panasonic, Toshiba and Sandisc memory cards. If it is not one of those three brands I would go buy one of those brands. Make sure you format your memory card with the camera before using it for the first time. As for the other memory card try using a program like cardrecovery.com and see if you can still pull your pictures off that card. I bet they are still there. :)

that happens to me sometimes with other programs. sometimes when you exit the camera, it doesnt completely exit. you have go to TASK MANAGER, then applications, there you can completely stop the application, and it wil open for you.

take it off the cradle try again if it dont work tfer the pic on a cd at any walmart. then format the memory and try again. if it still does the same you might have a bad memory card or bad reader.
