I cannot find out how to disable the Android One boot sound.
Does somebody know how to do it ?
Thanks for answers.
Pressing the volume down button had no affect on my 7 Plus. The phone vibrated, as if the key presses registered, the display dimmed a little and I still got the full volume chime. In fact, doing so reset the home button (it asked which launcher I preferred). MANUALLY setting to do not disturb stopped the chime (a valid workaround). I suspect I will adjust my auto do no disturb hours to include the time up to when I leave my house in the morning, and manually remove DND when the phone is running.
