Whenever i tap the camera button, it shuts down. Same applies when i want to listen to my music. I wait for a few seconds and then it shuts down, or it only shows some of my recordings/wav files and not any MP3 files. This happened after i put some songs on my mobile, i can assure you that the songs have nothing to do with it, and i still have enough of memory on my mobile. It sucks because i like photography. Thanks in advance!
