Sorry, but I never found where it is
Any suggestions about the place? I think other settings is fine, also it's the same settings you can manage with the wheel icon during calls
Something like:
≡
âš™ Settings
✆ Call & Device Settings
...or just in Advanced.
They are in Advanced right now, and you can also reach them during calls pressing on âš™
Very-very thx!
The item disappeared again, but since it just duplicated w10 "App volume and device preferences" — I don't think I will miss it very much.
All settings are now available in call.

Also webcam can be changed during video call.
Sadly, this prevents pre-call setting all up.
