Few Governments (like Japan) forces the Mobile company to have a Click sound when taking a Photo from there Mobile handsets. This is to restrict guys taking pictures of unalarmed girls at objectionable places. One of the affected company is Sony Ericsson. And the latest one to get affected by this rule is Apple’s iPhone and that is only in Japan.
Many people don’t buy “Sony Ericsson†(Cybershot) handsets due to sound while taking Photographs, which causes attention of crowd while taking pics even though Sony Ericsson Cybershots provides best Image quality.
But i have the trick which can avoid this sound, !!
Disabling the sound in some models of SE like W810i, is even simpler. Just put the phone in the silent mode and click! click! click!!
Congrats , you learn to take Picks without creating sound.
Happy shooting.
