Ah, are you using GPS on your phone at the same time?
You might need to go to settings and set dual audio ... So it can do 2 lots of audio (GPS voice and music) at the same time ...
Not sure if the smaller model does this
If I helped or solved your problem, please like or tick solved.
Have been using phones since 1993, and am self taught.
I offer advice for free, cos I think it'll help, if it doesn't, explain why, I might learn something new too.
Current phone Galaxy S22 Ultra
Previous phones: most S series, Note 2, Samsung Alpha, iPhone 3gs, far too many Nokia's!
