I have a radio app on my Nokia G21, buts its kinda shitty, hard to navigate cant record and clunky. Im looking for another FM radio apps, I only found ones that use the internet, and do not take the signal from the phones FM antenna, but from a server. I dont know if this can be accessed by any app, sadly I cannot root(Cant unlock bootloafer), but I can use ADB or shizuku.
Not sure about apps either, but if you’re into it then I can defo recommend getting a SDR-RTL dongle, they’re really quite cheap too.
