Since upgrading the iPhone 5S to iOS8, and more recently upgrading to the iPhone6, I have a random Tri-Tone alert (or vibration on silent) that goes off throughout the day. It could be a single alert at sporadic times, or occasionally it could be two a few seconds apart. But it would definately sound like an alert for an incoming message, mail, reminder, appointment, etc.
But........
I don't have any of those common alerts set to a Tr-Tone sound. In fact, I don't (knowingly) use that sound at all.
Since it didn't happen prior to upgrading to iOS8, I figured it must have something to do with the new apps that came with the upgrade. Nothing in settings for any of them shows that alert.
To diagnose, I started turning notifications off for each app one by one in order to identify the offending app. It still went off. Even without any apps listed in notifications.
I'm scratching my head. And hoping someone out there in the iMore-sphere might have a suggestion on where else to look.
