When I connect my Major 4 headphones to the phone using a 3.5mm cable (I have 3 different ones, the issue is reproduced on all three) the only thing I can hear is very loud white noise. Headphones themselves work fine when connected to other sources of sound, and my zf9 seems to work fine with other headphones.
I experienced the same issue on zf8 a long time ago.
Can you share a log file?
I generated the logs but I'm not sure if they are safe to share them publicly here on the forums.
is there a way to share them privately ?
Update: just figured out how to send a private message, sent you the logs, thank you !
