Very disappointed that the Lumia 928 has been excluded from getting the official Windows 10 Mobile upgrade, and removed from the Insider Program. I had little hope that Verizon would do the right thing and enable the Lumia 928 to be upgraded. However, I did not expect that Microsoft would pull the plug on us Insiders. Yes, the Insider builds have been somewhat buggy, but they are getting better will every release. The main issue that I have is with Group Messaging no longer working, but I don't get a lot of group messages, so this is just a little annoyance for me. However, I know the fix for this and to optimize W10M for the Lumia 928 would require a firmware update from Verizon. Obviously Verizon is not willing to do that. Hopefully something changes. I am encouraged that Verizon is still selling the Lumia 735 and it is on the list for getting the update. I may be willing to go with the 735 if it gets the official update on Verizon, and until a Window 10 flagship device is available, maybe the HP Elite? I will see how the last of the W10M builds run on my 928. I just updated it will the latest build release yesterday. At least they haven't cut us off yet.
