This application is useful for those who are unable to configure the camera shutter sound. (eg in Korea or Japan, etc.) IMPORTANT NOTICE: if you delete the application without manually disabling silent mode, silent mode will remain enabled and you will have no control to disable it again. In this situation, simply turn off the device and then turn it back on. Description: This is necessary to properly stop the silent mode by capturing the origin of the incoming / outgoing call and the call’s exit points, since if the silent mode is active, do not no sound is emitted. Required: You can use the app normally without having to grant this permission on Android 6.0 or later devices. At the moment, you don’t have the function described above. Devices with Android 6.0 don’t have the ability to selectively grant permissions, so this permission is automatically granted.
