To enable FR radio in a smartphone you need to plugin the earphones in your device as they work as antenna for receiving signals. It is kind of odd thing but a necessity to make FM radio work. XDA developer DaRk-L0rD has come up with a mod which allows you to enable FM Radio without headset in Xperia smartphones. Your handset must be rooted for this mod to work on.
