I'm on RTM. I've removed and reinstalled several times. Same with other head sets. Seems to occur when I start a call in Wi-Fi and then leave the building. I know the call isn't on VoIP. 950XL on 10 has been a bad experience for me: Freezes, wakes up at 10% brightness, etc. It feels like a beta OS that has been abandoned by the vendor.
Kwright, I know I have had a great deal of trouble with regards to windows 10, and Bluetooth, the last couple of years; I even had to convert back to windows 7 after the Windows AU update on one of my notebooks...the problem there was that the generic drivers issued by MS were not doing the deal, and the notebook manufacturer (HP) doesn't feel it important to update their drivers for past models
.
That said, depending on the connected device, "it could be" the drivers of the device (in 'SOME' instances); ALSO, I know in the past there were some builds that were problematic for a LOT of users (
most all of them for me, prior to build 15051).
If you feel impatient for some progress, insider SLOW ring is now on build 15051, I found this to be the START of the BEST experience I have had with my 950XL, and am 'very' happy with the current FAST ring: build 15055.
Or, you can wait a couple weeks when Creators Build rolls out to RTM, it really does look 'to me' that they have addressed most of the issues with BT, again 'at lease for me it does', and hopefully this will cure your ailments
And you are correct...the last year has been a test of attrition.
Good Luck!
