>>24154025It means there is a device in her house that isn't shielded properly or is transmitting, ever wondered what these weird lumpy bits on cables are? That's a ferrite core and it's used to shield electronic devices from other eletronics signals, if it's not related to her phone or any of her devices then that means a previous occupant or the landlord left an electronic device that can receive and send signals, sometimes builders leave radios plugged in weird place like an attic when doing insulation and it's benign or a roommate could be recording her for some reason
Those tiny cameras people use to record people in the bathroom while they shower? Yeah like those, the cheap chinese ones often create feedback and will pick up on bluetooth shower speakers, the smaller and more covert the device the worse shielding it has typically
