'Bit and bandwidth upscaling' option for some reason will not allow me to use it anymore. I don't exactly know when it became grayed out, but I know when I first got the phone I was able to choose that option and now I can't. Also I noticed a substantial volume and clarity difference between listening to music through Bluetooth vs AUX. Bluetooth I found to be much more clear and somehow louder than if I was listening from the AUX.
Oh, and on a separate note, Dual Audio is no longer available like it was on my S9. That was the only reason I got 3 sound bar systems in my living room alone! Bring it back Samsung!!!
