Ghost alarm

Hello, Dave7150!

Thanks for reaching out to the Apple Support Communities! It sounds like you have an issue with an alarm going off on your device even though you have no alarms set. Let's start by checking to be sure you don't have Bedtime set up. Check out this article to Use Bedtime to track your sleep on your iPhone and be sure Bedtime is not turned on.

Was the device reset and set up as new or restored from a backup?

Let us know the results and have a great day!

Thanks for getting back to us, Dave7150!

At this point, since you got the device factory restored abnd still have an issue, we would recommend reaching out to Apple directly by checking out this link to Get Support and they will be more than happy to proceed with additional steps.

Cheers!
