Samsung Galaxy SIII

[Android Central Question]

Samsung Galaxy S3 - A few days ago this phone started making the sound of a small bell rung briefly. I've watched to see what it is linked to and cannot figure it out. It does not seem to coincide with any of my incoming texts, emails, messages, etc. How do I make it stop. It is frequent and annoying, to say the least.

Does it persist in Safe Mode?
