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.

A full tutorial is given by the developer on how to enable FM Radio without headset in Xperia smartphone so you can easily do it by yourself but if you are a noob and don’t know about compiling and decompiling stuffs then you can directly install the modded Radio3.apk file to enable FM Radio without headset.

    I tried way #2, downloaded the ModdedRadio3.apk, and replaced the original one. Therefore I copied the originial one to a folder on my sd-card, deleted it from the system/app-folder, copied the modded one there and set the correct permissions. Then I rebooted. But now the modded radio app is not accessible through the user interface. It is shown nowhere, not in preferences/application nor in the Android “desktop”. But it is still in the system/app-foder.
    Can you help me?
