I installed LineageOS on my Samsung device, and there doesn’t seem to be a radio app. I have access to an identical device which is running the stock OS. I extracted the radio app on the other device (with App Manager) but cannot install it (unavailable shared library com.samsung.device). (Galaxy A21s, Exynos.) How can I listen to the radio on this device?
It is not FOSS, but it is usable as a webpage instead of an app. https://radio.garden/
Are there ads on the webpage too? Who knows, that’s what adblock is for.
Putting a proprietary app into a web page doesn’t make it not proprietary. And, if it’s using some web server to replace the built in radio, it may be Service as a Software Substitute too.
