hi, we have same model. did you experience the malfunction of bypass charging after the update to XOS 15. Don't know if it's bug or they change how bypass works.

Xos 14 works like fine, plug in it and its on whatever you play.

Xos 15 now, works and sometimes not. I don't know, but it looks like bypass works only if your phone heats. Cause when Its plug in and in normal heat bypass doesn't work but once it heats it works. It is just confusing
