I like the T-Mo jingle as much as the next guy, but is there anyway to shut off the start-up jingle when you turn a Revvl on? I can't find any setting for it.
If there isn't, maybe this is something T-Mo could add in a future update?
Turn the volume all the way down before restarting or powering it off.
There is no way to actually turn off the boot up jingle. Like mentioned before your best bet is to turn off the audio before a reboot.
