please tell this i didnt find an option anywhere..
Hmm.. If that doesn't, may I suggest 3rd party apps? Check out apps like Silent Camera (link) that can take photos and videos without making a sound.
That doesn't help at all. There is no shutter sound option in settings and putting the phone on silent still gives the sound.
Check camera settings first, some have options there to disable shutter sound. If there's none, simply put your phone in silent mode.
