I make an application to download and play mp4 video in nokia 311. I try to run the FM radio before running the application. when the application download video and then play the video. FM radio is off or muted. after the application finished playing videos downloaded and stop the video. FM radio back on.
how to turn off the FM radio before the application starts playing the video. so that when the application finishes playing a video and turn it off, FM radio remains off or silent
