I maaaay have taken my phone on an accidental trip in a pool and was given an old phone to use as temporary. Has a headphone port. Saw the radio app and realized how do many of my smart phones even had radio access even though they all are capable. Bastards
You must be close to a station. I think normal fm stations are expected to work at least 40km away, but I doubt you can receive it without a good antenna at that distance.
It’s not very far but it’s also a national broadcaster with especially strong signal I think
