Android doesn't show which codec is active when playing audio (except deep in developer options). It would be great if EarFun app could show the active codec. It already does it for AptX, but not for LC3, AAC, LDAC or SBC. It would help a lot in debugging.
Also, "Bluetooth audio quality" and LE Audio menus should be combined. If LE audio is not compatible AptX and LDAC, the those options should be automatically turned off when LE Audio is turned on.
