The North American spec S8 uses a Qualcomm Snapdragon 835 SoC which includes an FM receiver. An app called NextRadio can playback from the FM radio. Unfortunately, Rogers disables the FM radio, probably due to the customer insulting motivation of increasing data bandwidth consumption. I purchased an unlocked S8+ directly from Samsung, with an enabled FM radio. On use of a Rogers SIM, the phone downloaded Rogers specific firmware which disabled the FM.
