The phone calls became almost unbearable, if you manage to hear the other side at all, in the last few weeks. Not sure if it's my OP6 broken or it is a general issue. Haven't had a chance to test on my POCO.
@wannoye I am in the same boat with my #oneplus6 with #postmarketos edge. It seems audio for the "Earpiece" is very distorted. I have filed a bug report.
@tomasoqvist Thanks!
