I've got a Sony Xperia Z3 Compact running Android 5.0.2, and is not rooted, which has a button that instantly wakes the phone going straight into the camera app.
One problem - unless Media Volume is at zero, pressing the camera button makes a distracting and annoying tinkling sound.
It does this despite the fact that:
- I already have "Sound" turned off in Camera settings. This turns off noises like the shutter sound, but doesn't stop the camera button sound. It seems the phone thinks "camera sounds" and "camera button sounds" are completely unrelated things.
- I've turned off all the Sound options under the phone's system settings.
How can I turn off this specific "camera button" sound? I've looked through the system settings but can't find anything relevant.
Right now my "workaround" is to always turn media volume to zero after every time I do something which uses it, but this is far from ideal.
