I looked up and down but did not come across anything.
Is there any ADB command or android way to to turn on FM in an android phone? Or i will have to create and app to do this?
You might be able to use Activity Manager commands from adb
adb shell am start -a <some intent>
or
adb shell am startservice -a <some intent>
but you should read the question Android Intent to launch radio application
Unless you can find out what the intent is called then you may be completely stuck.
