Want to turn off your device’s camera sound? Try updating your software:
iOS devices
Plug your device into a power source and make sure you’re connected to Wi-Fi.
Go to “Settings” > “General” > “Software Update”.
You may see two software updates – pick the one you want to install.
Reminder: iOS 15 removes the shutter sound on devices outside Japan and South Korea with an active non-Japanese/non-Korean SIM card.
Android devices
Go to “Settings” > “System” > “System update”.
You’ll be able to see your update status – follow the steps that appear on the screen.
