This has happened a few times. In my sitting room, I occasionally hear a mobile-phone vibration sound, like a silent phone just received a notification, but it’s not coming from my phone.
It’s near to the wall joining us to our neighbour’s house, but it really sounds like it’s coming from inside our room. Is there a way of finding it? I tried the Bluetooth “find devices” option but nothing came up. It’s driving me nuts!
