Hello everyone. I'm new to the forum. After changing many Xiaomi phones and custom ROMs, I finally bought a Pixel 7a. Among other things, I wanted to try GrapheneOS. I installed it using the web installer. My impressions so far are very positive. One thing that seems a little strange to me is that I have a .database_uuid file located in Pixel 7a\internal memory\Pictures.thumbnails. Is this okay, should I be worried that something got into the system? I had this file on my Xiaomi phones and couldn't figure out what it's for. PS. I haven't installed the Google Store on GrapheneOS, but rather Aurora Store and F-Droid. I haven't even logged into my Gmail account. Is this actually some kind of tracking/spyware file, or should I not be worried? Thanks a lot! :)

    It is a static text file, and is part of AOSP, to identify stale thumbnail collections. It is normal and nothing to worry about.

    As per the AOSP source code: https://android.googlesource.com/platform/packages/providers/MediaProvider/+/master/src/com/android/providers/media/MediaProvider.java

    /**
    * Hard-coded filename where the current value of
    * {@link DatabaseHelper#getOrCreateUuid} is persisted on a physical SD card
    * to help identify stale thumbnail collections.
    */
    private static final String FILE_DATABASE_UUID = ".database_uuid";
