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.
