I just tried a wired headset (with an aftermarket dongle), and didn't have any problems. No idea about the bug, sorry...Hi!
I've just installed this ROM with the procedure of this thread (flash stock ROM, format and change filesystem, flash ROM, root with magisk canary) and I 'm having a weird bug. When I connect any headset (wired or bluetooth) the screen goes black, as if the system process failed suddenly. Any suggestion?
I don't think it really matters here, but why did you use Magisk canary? The stable v.23 works just fine.
