Known Issues Identified with Windows 10 Mobile Phone 10 Upgrade

Microsoft has already identified and documented known issues with Windows 10 “Technical Preview 2” release on Windows “Lumia” Phones. I’m sure people will have more issues than the ones which Microsoft documented. Don’t worry, it’s still Windows 10 technical preview version and it’s not a production version of Windows 10. So Microsoft has enough time to fix “most” of those issues before production release of Windows 10. Keep updating about the issues which you faced on Windows Phones after Windows 10 upgrade. I’ll try to keep this list updated.  For the moment the list is same as Microsoft’s list. Microsoft has released Windows 10 Technical Preview version to a subset of Windows (Nokia / Lumia) phones. More details about this in the previous post here.

  1. I’m not sure about them discontinuing the Call + SMS filter, but I’m having problems with it too. I was trying to block Kelsey’s number but I when I try, it just goes back to the home menu.
