Tune into the FM radio, although the green icon appears on the screen, the sound does not come out, that being the headset plugged into the cell phone, the sound should come out loud. Now in MP3 or MP4 recording on bluetooth ai if sound comes out loud without using the headset. Before the radio was heard with the normal headset. It must be some configuration that has been modified, but I can't find where the error is. Can anybody help me ?

Your explanation is somewhat confusing, but if the only application that causes the headset and the horn to generate faults is the FM radio means that there is corrupted data in the application, so I would recommend you uninstall and reinstall the application to see if your problem.

Thank you for your video, you solve my case. Muito obrigado, Benny
