I try to go into

Question

I try to go into the "Take Photo" or "Record Video" function of my Samsung Z510 and it does not work, It starts loading and either goes back to the wallpaper screen before it finishes loading, or comes up with the word "Abort" and then goes to the wallpaper screen.I have tried holding the camera button on the side of the phone and the same thing happens.There should be no reason why the camera does not work and the phone is in great condition.Please let me know if you can help!
