My FM tuner stopped working after the February 2021 android update on my Galaxy S10 plus unlocked. Worked fine with Nextradio prior to the update. Nextradio app says it cannot access the FM tuner. Any fixes?
Same problem here (factory unlocked US version Galaxy S10). T-Mobile said they cannot fix the problem. Android 11 Release Notes only mentions the FM tuner in passing. Looks like an unintended consequence of tightening up security. Solving the problem would probably require an update to the NextRadio app (or Samsung Radio app). See below.
In Android 11, audio source MediaRecorder.AudioSource.RADIO_TUNER is visible as @SystemApi and using it when capturing audio with an AudioRecord or MediaRecorder requires privileged permission android.permission.CAPTURE_AUDIO_OUTPUT.
