Lumia 830
Upgrade from 10581 was successful. I did not reset 10581, and that upgrade was from Windows 8.1 Denim.
* Still no apps listed that are compatible with Glance screen, including MSN Weather. I also have Amazing Weather HD, which works on the lock screen, but not Glance.
* Lumia Help & Tips still won't update, with error 0x803F8006
* Weather and Groove Music have no icons in all apps list. They're just colored tiles. Weather also doesn't work on Glance, as noted above.
* Motion data under Extras in settings is blank.
* Just got the black screen flash bug, where the screen goes black for one second or so and then comes back.
* Some websites still don't have favicons when pinned to the home screen. They're just the Edge icon.
Other Issues
* Still no working live tile for Wunderlist, but I think that's on their end, and they know about it. Not having a list I can see is like going back to the stone age interface of PalmOS/iOS. (HEYOOO!)
* Sounds for alarms are really limited. Not many are more than a second or two long. Same with the previous build.
So far, this build seems about the same as the last one. It definitely hasn't fixed the (minor) issues I had with that build. I don't necessarily want to hard reset and lose access to Here Maps. I'll chime back in if I run into any other bugs.
Edit - one fix - Waze opens without crashing on this build and didn't on the last one. Not sure that it actually works though. It gets stuck on calculating route.
