Galaxy S8 came out in 2017, almost a decade ago. I understand some budget and mid-range phones have ads, but I (in Canada) have used everything from S7, S8, S12, A51, Z Fold 3, and have never gotten one. There was a "Samsung Hub" app on the midrange A51 (similar to Google Discover), but that can be disabled.
I had a Galaxy S8. It definitely did.
> Unlike iOS,there are any number of music player apps on Android that stay out of the way and don't try to be a "platform".
iOS has other music players too. It was a choice that e.g. doubleTwist stopped supporting iOS when pivoting to CloudPlayer.
