Hi, I am new to this forum, I have a 950, I was wondering if this device (Hd10) works when the phone screen goes blanc? Seems pointless casting to a larger screen and having the phone screen on too, is there a feature for the phone screen to sleep/turn off and the youtube clip still plays on the big screen for example, I very much doubt this but thought I would ask anyway, also continuum not working via this means..... that's not so good.
