How can I get my volume levels to synchronize? I have to go all the way to the volume level settings and do each one if I want the phone to be silenced.
I've tried that myself and although ring, system and notifications mute media and bixby still work.
The only way I believe to mute the whole phone would be put it on do not disturb, seeing it's 12.46 am here and my device is on do not disturb I don't want to mess with the setting to test it out seeing I've never tried it myself. Then again that can't work either seeing I'm no DND and I got media and bixby to play sounds.
I guess there is no universal setting to turn all sounds off with one stroke, hitting mute and then media and bixby might be the only way.
