I noticed that FM radio is only in Mono when I listen on my wired headset. All my previous Samsung phones with FM radio where able to receive in Stereo but my new Xcover 4s (SM-G398FN) can't. I noticed the chipset is capable to receive Stereo FM so it must be a bug in the App or driver. So Samsung please fix this issue.
And while you're at it fix the missing resolution option in your camera App asap as well. It's been reported in September 2020 and still not solved!!!
