I also facing the same problem, but I still cant find out what kind of setting will lead to this result, is that the problem of the software( Android 8.1) or the hardware fault?
Same issue here. When it occurs, the only workaround is to restart the phone... until the problem occurs again. Very annoying.
Already reported. The only way to listen is either through bluetooth headphones or through the loudspeaker itself...
I´m curious to see how Nokia address this issue. if not, i´m going straight back to motorola for sure ;)
