Big thank you, mate. Even in India where there is no law prohibiting silent screenshot and silent photography, Google completely removes the option to silence camera shutter sound. No VPN or mock location helps here because this is based on the inserted SIM card.
Earlier, the only option to silence camera shutter was to go to /data/data/com.google.android.GoogleCamera/shared_prefs/com.google.android.GoogleCamera_preferences.xml
then change this value to 0:
But inexplicably, the value would nastily reset to 1 from time to time and you would get a rude sound when expecting a silent camera shot.
Thanks to OP, I just extracted his zip and replaced the original /system/product/media/audio/ui/camera_click.ogg
with OP's camera_click.ogg which in fact can be created easily as a new empty file.
Thanks to OP once again from the world of chains and fetters, gags and censors!
