There are many things in the phone that the developers may think has higher priority than the FM radio. And as they work for free, may we need to do some things our selves, if we want them really much. And FXP does accept contributions (if you or someone else gets it to work).i will have better luck learning the programming than get my fm radio ?
It is properly either a driver problem or there needs to be made a "connection" between the driver and the CM compatible FM apps.
