I had turned on "Ok Google" and configured it listen "From any screen". Looks like Google try then listen all the time and blocks FM Radio output to headphones and also to speakers
Here is my first mod after getting a own Z2. FM radio without head phone. This mod needs a fully deodexed rom. Tested in stock deodexed 167 rom. Works well. So i am sharing it here.. I know there is a xposed module available for this. But my mod is for the peoples that they don't using xposed.. Pls note. This mod needs a fully deodexed rom. Always make a backup before trying any mod. Do not blame me if anything goes wrong...
