The implementation mechanism of mobile phone camera sound mainly involves dual control of the system layer and application layer:
1.System layer: The Android system manages sound output through the AudioManager service. Silent mode will terminate all non-emergency audio.
2.Application layer: The camera APP can call the getStreamVolume() method to detect the current volume status. Some manufacturers will force the shutter sound to be played.
3.hardware layer: A few models use independent audio chips to process the shutter sound. In this case, the firmware needs to be modified to completely turn it off.
