On the iPhone, it is accompanied by sound effects that notify us of the start of video recording or of a successfully taken photo. Personally, the sound of the iPhone camera shutter does not bother me at all. But it turns out that some smartphone users who take a large number of photographs of documents in a cramped office find themselves in an awkward position and even think about changing their iPhone to another. Since this sound of the iPhone camera does not allow fellow colleagues to concentrate on doing their work.
As you can see, sometimes there is a need to mute the iPhone camera. Especially for such people, we decided to write this note. The fact is that while the settings of the iOS operating system (today it is 10.3.3) do not allow you to remove the sound of the camera click, although everything is not clear here.
Muting iPhone Camera Click Sound
Let's look at an example, iOS 10.3.3, batch number MN9M2LL ways to mute the camera: (for which we indicate Part No. you will find out at the end of this post)
- The easiest way, for most iPhones, is to turn on the toggle switch on the left side of the phone itself. When you turn it on, a crossed out bell appears on the screen, and the signature at the bottom - Silent.
- Another way to turn off iPhone clicking camera sound. We launch the application or, turn on any track or podcast, set the volume to zero. We minimize the application with the button, launch the Camera and take a photo or video without clicking the shutter.
At the same time, the melody playing without sound can be paused so as not to drain the battery.
IPhone Live Photo - Works without camera sound
- In the standard Camera application, turn on the Live Photo mode, pictures are also taken without clicking the camera.
- Well, the last official way is to try from the App Store that allow you to take pictures, for example, the Microsoft Pix Camera and others that allow you to turn off the sound of a photo in the settings.
If the methods above still do not turn off the camera sounds on the iPhone, then the laws of the country for which your phone model was released prohibits taking photos and videos without a notification sound. At the moment, there is such a law in some Asian countries: Japan, South Korea and, if I am not mistaken in China.
When shopping for iPhones, look for one that will help you find out, this is especially important if you want to mute the camera shutter sound.
Therefore, an office worker from Japan can only do and install from the Silent Photo Chill program.

There are other clumsy ways to enable camera mute in iPhones, but they do not work in all models, some users were helped by connecting headphones, after which the click disappeared, some after jail digging into system files, renaming the photoShutter.caf file responsible for the camera sound. What helped you, write in the comments.
As iPhone owners have probably noticed, when taking photos, the camera is accompanied by a characteristic sound. Many users do not pay attention to this sound, but sometimes there are situations when such "musical accompaniment" can interfere with others, for example, when you need to photograph a lot of documents in a small office space in which other people work besides you.
There is currently no option to turn off the shutter-click sound in iOS settings (but there is an option to turn off keyboard clicks and screen lock sounds), however there are a few tweaks to do this.
It is worth noting that in some countries filming with a camera without sound is prohibited at the legislative level (Japan and South Korea), therefore, it is impossible to disable the camera shutter sound in the iPhone for the markets of such countries without jailbreak.

How to turn off camera sound on iPhone
To begin with, the volume buttons located on the edge of the iPhone can only reduce the volume of the camera shutter sound. Moreover, it is necessary to reduce the sound when the Camera application is inactive. Otherwise (when the Camera application is running), the buttons function as a shutter release.
The easiest way to completely turn off the camera sound on most iPhones is to activate it using the toggle switch on the left side of the device. When the mode is activated, the display will show an inverted bell icon with the inscription "Silently".
Another way out is to launch the "Music" or "Podcasts" application, turn on a song or podcast and turn the volume down to 0. Then, turn off the program using the "Home" button and activate the camera. Shooting will proceed without the shutter clicking. If you don't want to drain your battery, pause the track or podcast that is playing.
Note that when shooting in Live Photo mode, the camera also works without sound.
Finally, you can download camera apps from the App Store, such as the Microsoft Pix, that can be configured to turn off the shutter click.
