about a few days ago i discovered an unknown file in my downloads on my phone (Samsung Galaxy S21FE).

It could not open it on my phone so i just transfered it onto my pc to open it. It contains somethig that looks like Hex-Values "91e1f39[...]092abb0e2333b8f2e" (in the [...] are more of this).

I doesnt have any extension, or information where it comes from. It just has a name "testing". When i delete it, it randomly appears on my phone a few days later...

Do you have any idea what this could be?


  • This may be interesting for this: once i was in a public space i got bombarded with bluetooth-pairing requests. like someone is using a Flipper-Zero with Bluetooth-LE-Spam. I dont know which scenario came first..
