Question Random Ghost sounds without notification

[rockysinghmn]

I have S23 ultra with t-mobile running Android 13.

My phone plays a notification chime every morning at around 9:00 am Eastern (+/-15 min). There are no notifications/alerts. I have checked notification history. Installed Nice Catch app but could not find the culprit. I am not able to find the the sound as I checked and went through all the audio and sounds in my phone.

I recently travelled to mountain time zone and since then I have been getting the alerts at 11:00 am Eastern (+/-15 min). So, it moved to mountain timezone. This is driving me nuts. Please HELP!

Welcome to Android Central! Any Google Assistant or Bixby alarms/reminders set up?

I had some reminders. I have deleted them and will check if I get notifications again. Thanks

The issue is still there. Any other ideas?

Does it persist in Safe Mode?
