Silence camera on Samsung phones
Android 14 blocks the APIs needed to modify secure settings. As such, this app will no longer work on Android 14 and above.
Thanks to Matthew Wright for letting me know of this problem.
Install, open, and click on the switch to enable the mute function. Click on the lock icon to enable on boot.
Turn off the switch, then uninstall. If you uninstalled before turning off the switch, re-install the app, toggle the switch at least once until it is in the off position (so if it shows as off, then turn on and then turn off. If it shows as on, just turn it off), then uninstall.
If you still get unexpected behavior after following the removal steps, try the following command on your computer while your phone is connected via USB and in ADB developer mode:
adb shell settings delete system csc_pref_camera_forced_shuttersound_key
This deletes the prop set by camsung.
Please do not use this app for malicious purposes. It's only made for situations where you don't want to disturb other people (such as in restaurants or in a library).
This app directly modifies system settings. While it should be relatively safe things can still go wrong. I am not responsible for any problems that may arise from using this app.
This app only works with recent Android versions paired with One UI releases. Future software updates may block the mechanism that this app uses.
