I think most phones only support max 48khz. But some phones like Samsung a53 ,a73 and s22series does support upto 192khz I checked through fiio app for ka3 so I don’t know whether it’s correct or not but when I played with same settings with other OnePlus 11 r the sound differs lightly and volume is low with OnePlus but with Samsung I can hear the difference
