Lumia 930 - Really pleased with this build, had an issue where notifications weren't showing on lock-screen, but sorted this now. It hadn't retained the settings in the lock-screen page, so the apps I wanted to show up were not in the list, have put them back and it seems ok now. Apart from that, a few minor bugs here and there, but nothing major at all, using it as my daily driver without issue, battery life pretty good, about the same as 8.1, but can drop quite quickly on occasion, but this tends to be in the evenings when I'm playing games. Outlook asked for a pin initially a few times which I found odd. News app asks for location almost every time I open I open it, a minor niggle. Lockmix works ok, so I can have a prettier lock screen
Just noticed another minor issue, after swiping up to unlock, my lockscreen image stayed there instead of the tiles showing, but simple press of the home button brought up the tiles, again minor. Looking forward to the next build.
