I hate to start a thread because I asked in another one but it just got pushed back a couple pages and lost so I'm trying again hoping there are some ideas. I am having an odd issue since the Marshmallow update. On some days at either 4 or 5 pm the T-Mobile jingle goes off a bunch of times. No notification or call from anyone and no alarm to shut off when this happens. In fact I can't stop it without just turning the volume down. Anyone have any ideas what it could be? Again it does not happen every day, maybe 3-4 days a week and it's either 4 or 5 pm but not both. Nothing shows up in the notification tray so it's really confusing.
