How to find which app is playing random fanfares?

[Craig MacKenna]

Every day or so, my LG G6 phone (VS98830b) plays a short fanfare without giving any other sign of what it's doing. At first we weren't sure it came from the phone, but now I've held it in my hand while it happened. Seems like it must be a sneaky app, but how can I find which one?

Which phone? Is it a Samsung?

Hi, which phone ?

If you try safe mode and doesn't happen most likely a 3rd party app , if that's the case try uninstall the new ones and work backwards 1 by 1

LG G6 (VS98830b). But if I'm correct in suspecting an app, which phone might not matter much. Android version 9, Kernel 3.18.120

Definitely matters, if you would have said Samsung I could give you other options to trace this .

I can only think of two small interface apps that may have been added since this problem started. One is called "Fuel Card" and the other "GoodRx". Please remind me how to restart phone in Safe Mode.

Restarted in Safe Mode. But with fanfares that play a few times a week, it's hard to know when this has proven the guilt of a 3rd party app. If it does, is "disabling" apps as good as uninstalling them?

If you can disable but usually 3rd party apps don't have that option, it's mostly some built-in apps do

Have you already tried turning off NFC?

 

[Laura Knotek]

@Mooncatt, are you aware of any LG apps that might cause this?

 

[Craig MacKenna]

I don't think that any NFC has been enabled.

I don't think that any NFC has been enabled.

Start with those 2 apps you mentioned or se if this app helps find it

Ok, and just to be sure -- you don't have a case with a credit card holder on the back or on a flip cover?

mustang: right now I'm following your Safe Mode suggestion. I'll give it 3 days, if no sound then try disabling/uninstalling 2 new apps. The trouble with toastsource is that it's driven off messages not sounds. Can I contact author Jakubowski somehow and ask if it will notice fanfares?
Diddy: phone naked other than rubber back.

There's a big chance that sound created an entry in the notification log, showing which app pushed it. This guide can help you to access this log. Being an LG device running Android 9 it's possible that you will need to use Nova launcher or a similar app.

Ok sounds like a plan

My Samsung flip 4 does this. What should I check.

Can you describe what the fanfare sounds like?

I recall a similar thread in the past about a 3-tone sound that occurred without any notification icon. This seemed to be due to a local news/weather app from certain NBC affiliates (the 3-tone sound being the NBC jingle).

You try any of the suggestions in this thread?

Have you tried the Nice Catch app from Galaxy Store?
