On some phone models, this feature cannot be disabled. Here is what this clicking noise is initially for.
Most people who own a smartphone agree that there are certain default settings in their device that they would do without. Like the clicking noise made when you take a photo with your camera. Generally, it is possible to deactivate the sound by switching to silent mode for example. But this functionality is not possible on Japanese cell phones and many users are affected, especially if you have a refurbished smartphone or if you bought it abroad, in Asia.
This specificity exists for a specific reason. Indeed, it serves above all to protect users. Since the 2000s, Japanese manufacturers and telecom operators have agreed that all smartphones should always emit the characteristic camera click, even if they are in silent mode.
But then why? To combat malicious use, particularly the taking of unauthorized images in public and private places. For example, photos taken under women’s skirts without their knowledge. In Japan, voyeurism targeting women and girls is a real scourge, particularly on public transport. In 2015, the Japanese government strengthened this agreement by amending the Ordinance on the Healthy Development of Minors (Japan’s Ordinance on the Healthy Development of Juveniles).
If your smartphone is affected, there is nothing you can do about it. On the other hand, with a recent iPhone equipped with the latest iOS update, this problem is normally resolved. The iPhone normally adapts the camera sound according to the geographic area detected by the cellular network. Furthermore, be aware that outside of Japan, South Korean and Chinese authorities have also implemented similar regulations for their phones. Keep this in mind if you are considering buying a smartphone abroad to save money!
