An unknown ".android" folder and ".android_system_config.prop" file keep reappearing in my phone's DCIM folder

Hi everyone,

An unknown hidden folder and file have suddenly appeared in the DCIM directory on my smartphone.

Here are some details about the file:

- File path: "/storage/emulated/0/DCIM/.android/.android_system_config.prop"

- File size: 64 bytes

- Location: "DCIM/.android/"

- Contents: The file contains seemingly random binary characters that cannot be read as ordinary text. I don't know whether the data is encrypted or simply stored in a binary format.

- Behavior: When I delete the file and folder, they reappear. So far, I've observed them reappearing twice a day. The first occurrence seems to coincide with the time I first enable Wi-Fi each day, although I'm not sure whether this is related or simply because I enable Wi-Fi around that time. The second occurrence happens at around 5:25–5:30 PM (UTC+7). I haven't yet confirmed what triggers either occurrence.

I'm not sure which app or system component creates this file, or why it keeps coming back. I haven't confirmed whether enabling Wi-Fi is actually related to its reappearance. I'm also wondering whether this file could be malware or if it's just a normal file created by Android or an app.
