I read my phone (Samsung Galaxy S4) has the hardware needed to listen to over the air FM radio stations just like I do on the car radio. The next radio app says it can organize and play the content that is being beamed all directions for free. No money to next radio, no money to subscription, no use of data since it is simple radio waves being picked up on. Their ad campaign says this could be only source of news in the event storm such as a hurricane takes out all the electricity and cell towers. Best of all since it is not data traveling on carrier lines there is no data usage. One catch. MetroPCS my carrier blocks the app. I am told I can root my phone and undo the block. but also told that has other consequences. So questons: Is my phone electronically capable of receiving FM broadcasts just like my little transister FM radio? If it has to be rooted where do I find instructions to do so.? And where do I turn if I mess something up?
If I cannot do this with MetroPCS as my carrier what carriers are out there who will let me use this built-in feature of my phone? Are there places I can take it where it can be rooted by professional who know how to root it without messing something up?
