Weird ringtone starts playing randomly and won't stop on Android A50

[Android Central Question]

This strange music that sounds like a musical ringtone keeps playing at random times. I've never chosen this music for my ringtone, and my notification sound is set to silent. And yet, this strange music starts in the middle of my phone calls and won't stop, or just starts to play for no reason in the evening. I've closed all background apps, ran an anti-virus software on my phone, and triple checked all of my sound settings, and I still can't find the source for this weird music or why it plays so intrusively. Can anyone help?

I uninstalled the last app I downloaded; photo slideshow with music, and it fixed the problem.

Welcome to Android Central, and thanks for the tip! Was the app actually called "Photo Slideshow with Music"?
