Pretty sure someone tried to hack my phone using a radio phone

at newport train station

dodgy looking guy sat down near me and he had two phones, a normal phone and a phone that he was trying to conceal under it that was a radio phone.

I was listening to a book on audible using wired ear buds, not bluetooth, bluetooth is always off unless at home

my connection to audible was cut and i got an error message. first time ever.

my phone is pretty secure and i have very little on it, no apple account access, no bank, etc

but still 🤨

I walked away , went around a wall and my audible connection returned

I am home now ( I always post here on my PC, not my phone ) and just looking thru my phone to make sure it's not compromised
