Android app installed by itself

[Susy]

Hi, this is the second time that I found on my home an app installed by itself.
I immediately deleted it, but I wasn't careful enough to look closely at the name of the app or to take a screenshot. My fault. However, it was named "Android system... something". It don't show up in the Play Store, on the "not installed" apps.

I did some research on the web, but I only found an app called "Android system safety core" that's installing by itself on Android phones. The problem is that the icon is not the same. The icon I saw on my home was black (on the background) and purple/blue purple (something like waves). I didn't found an icon like this in my researches.

Has anyone experienced the same thing or have some suggestion?
I have a Huawei P30.

I've actually seen something like that recently on my old 1st gen Pixel (that I keep for historical reasons). It seems like some Android system app that is either updating or being installed de novo by Google Play Services. I wouldn't be worried about it, but I can't give you a definitive answer just yet.

Thank you. If you have any news, let me know.

I'm pretty sure it was Android System Key Verifier. https://support.google.com/product-documentation/answer/15669061?hl=en

The icon was similar in concept (it had a vertical wave with two "hugging drops"), but it was black and purple...
I tried to download it to see if any icon update occurred, but nothing happened...
