MICA-256. Audition a notification tone; the same rules as previewRingtone.
Audition a tone from the settings pane. Ignores the ring mode (that is the control
being configured) but not the mute or the volume — see SoundService.preview.
Developer Tools' battery slider used to call charge.set() directly; that bypassed
this permission entirely, the same gap useClockWrite's setIs24Hour closed for
is24Hour.
MICA-256. Set the tone every notification plays, for the whole phone.
OS Service Hook for changing the phone's hardware (MICA-127) — signal, cell service, bluetooth, volume, the ringer, and (Developer Tools only) faking a battery level. Separate from
useSystemHardware(), which only reads it.
