It started today. It's like a ding-dong like I hear when I get a text. I turned off my phone, turned it back on and the sounds went away, but they are back again, and it's driving me mad. I looked up online and some people said it could be roaming sounds (my roaming is not on in settings).

I do have Malwarebytes on my phone, and before I swipe to get to my home screen, I see a notification "Malwarebytes has critical issues". I click on that and click "Fix" and nothing happens.

Please do not ask me to do a reset, I will lose hundreds of contacts.

Any ideas?
