Cell phone plays sound out of nowhere?

Since 10min, my cell phone sometimes just plays a sound like that. In the sound you can hear a short, quiet drum emitting a tone and several keystrokes. This just happens out of nowhere. It doesn't matter whether I'm on Google or on my hometab. (The keystrokes are not coming from my keyboard on my cell phone)

To be honest, I'm pretty paranoid etc. Which is why I'm just a little unsure whether something is on my cell phone.

Any tips to check if everything is okay? Do you know that too? (I have a Huawei model from 2019 if that tells you something).

Please do not write any assumptions. (Only if you really know it, or are very familiar with it) I.e. Don't write something like "I think you have a virus!" Because such assumptions just drive me crazy.

No is not a virus. I had that too, just close the background apps. There was some app with sounds that was still in the background.

and is the sound gone?

Thanks, I don't know much about cell phones. Still, I wonder what app that could be. Basically, I don't have any apps with keystrokes as notification, etc. But it can also be that I'm just too stupid for that.

Yes, games are mostly apps with sounds. And gladly! I'm glad I could help you

Yes that can be of course. ^^
