Hey this is a GREAT Build for the 930 - but the fine print is - as long as you Hard Reset after installation. I was coming from 8.1 Update 2, but Start Screen issues, missing apps and duplicate apps were all present. Was about to rollback and decided to try Hard Reset, Clean Install first - and I am happy I did - the OS is Gorgeous on the 930! My only complaint is I don't like the buttons on the application jumplist - I prefer simple, clean and plain - I don't dig the 3D shadow/highlight - but it's something I can live with.
Here is what I have noticed:
- Music App has to be downloaded from the Beta Store which I thought was weird. Be sure you eliminate an old device on your Xbox MusicPass. Once you do, restart - and guess what - MUSIC DOWNLOADS ARE BACK!!!! This is huge.
- Project Spartan works great - noticed IE is now completely gone.
- Store Account is SOLID - I was able to finally get the Lumia Camera Beta App for the 930
- Outlook Calendar and Mail works great (this was the final dealbreaker for me before..)
So in all - if you have a 930 on 8.1 and are willing to backup and do the hard reset - this is now a very nice little system - IMO now at the level of a true Developer Preview.
