So I have a V10 with the Marshmallow update and since then, some days the Tmobile jingle goes off 4 or 5 times at 5pm. I can't turn it off because there is no notification or anything saying what is causing this so I'm really stumped. I have checked various games, alarms and my calendar but if it was any of those things, wouldn't something show up in the notification tray? This does not happen every day, maybe every other day or every few days. I have done a couple factory resets after the update so not sure if another one would do anything. Anyone have any ideas?
