Another issue is Android auto. When plugging in the phone the screen will stay black until hard reset is done.
Workaround: open Android auto up before plugging in the phone. Once Android auto is running on device plug in and it should work as normal. This has to be done every time you want to use Android auto.
Phone issue persist still with other dialers, updated phone app, stable or beta. I'm believing it has to do with the telephony apk that is provided with the ROM. Maybe the cell broadcaster also.
Thanks for the workaround, unfortunately didn't work for me, so back to PE as this worked without a hitch, just a shame I can't select more 'accent colours' other than the 6 muted options....
