The only app "NextRadio" that I know of that supported the FM chip in android phones no is longer supporting this function. There are so many streaming apps to use now, and many FM stations ha ve their own streaming apps too, that FM chips in phones are now obsolete!

I have found one app called MediaU or something like that on the Play Store. It doesn't use the FM Tuner per se but it uses a location based service to locate the local stations. i think it uses some data.
