I see. misunderstanding. V60 has been released too in Japan, but it seems that there isn't report same issue.

If you're still having problems, try applying the beta version of firmware distributed for the Japanese Galaxians. If the problem between your V60 and Q5k is just same as in Japanese Galaxy, it maybe fixed. https://drive.google.com/file/d/1oNp_t0DIWUAwAeTNUBNnuDM30QQ49BTg/view?usp=sharing This...

ya, I'm watching thread. I tried all the suggested solutions before the thread progresses, but I see no improvement. display bitrate after firmware update, but displayed as N/A. I think so Q5k issue, because only issue with Q5k on my device. but if only Japanese version Galaxy issues, maybe...

all default BT settings. when I check in developer options and Q5k app, it show connected LDAC. since it plays normally on es100, I think so it's Q5k problem. I contact support. Thank you reply.

I finally received Q5k today. I've been waiting. but, no audio sound when LDAC enabled in Galaxy S8 plus. no problem SBC and Apt X. any solution I can take?
