I too have gone from my very trusty 928, first to a refurb which I returned on Amazon, then found a new Icon on Ebay. After completely setting it up I found I couldn't send a picture by text. The refurb camera button wouldn't turn on the camera and now this. Spent an hour with V and they found nothing. They suggested the windows device recovery tool. I hooked it up at 10:30 the other night, let it run and went to bed. The next morning it was just doing the same spinning. It did nothing, so that tool is worthless to me. I decided to give it a last ditch and reset the phone. It worked and now everything is working fine, even bluetooth, gotta have Pandora in my car! I kinda miss glance, but love Hey Cortana! I will admit battery life isn't as good as it is on the 928, hoping w10 will fix that. I use the 928 on wifi to save my 929 battery! Since I'm using this for my daily driver I'm going to wait until a complete and fully functional w10 is released before going for it. Funny what some of us will do to stay on big V, even they don't seem to give a crap about us! 735 my ***. Why go backwards from a 928. And a big NO WAY on Att or the 950.
In summary, I'd go for it, especially if you can find a new one!
