Everything wrong with Windows 10 Mobile build 10149

Microsoft delighted its beta testers last night when it launched the latest Windows 10 preview for mobile devices. But despite its many changes for the better, build 10149 still has a number of major issues.

First up is the update process itself, which is still missing its migration screens. What this means is that after the “spinny cogs” screen does its thing, users will see their lockscreen, instead of the progress bars that tell them the update hasn’t actually finished yet.

It is very important to let the phone rest until the time and date show up, alerting you that the update has finished. If you get impatient during this part and restart your device, the upgrade process will go wrong and will leave your phone “in a funky state”.

But that’s not all, there are some other, occasionally major issues, that you need to be aware of. Here they are:

  • There is an issue where the Install button doesn’t respond after Build 10149 is downloaded. Make sure the battery is charged >40% and press it again.
  • Some people may encounter an 80091007 error trying to upgrade to this build from Build 10136. If you hit this error, sit tight – we’re working on a fix. Or if you want the new build right away, you can use the Windows Phone Recovery Tool to go back to Windows Phone 8.1 and then upgrade to Build 10149.
  • The Insider Hub is removed in this build. Don’t worry, it will be back in future Insider Preview builds.
  • Sometimes the PIN keypad won’t be shown after swiping up to unlock. The workaround is to swipe down to get to Action Center and try to open a notification or Settings to invoke the PIN keypad to unlock your phone.
  • There is a very rare situation where you are unable to unlock your phone after entering your PIN and it keeps letting you type even though you entered your pin correctly. If you hit this – leave the phone alone 1-2 hours before trying to unlock again. This is caused by a TPM issue that could get worse and require you to reflash if you get into this state and power off the phone.
  • If a Gmail account is set up on the phone, the Messaging app may have issues and both incoming and outgoing messages may not work. If this issue is hit, simply reboot your phone to get it working again. We are aware that the Messaging app may behave badly in this state.
  • There is a known issue where apps or games are installed as trial versions even though you have previously purchased them. In-app purchases on Windows 10 Mobile are not functional yet as we migrate the function to the new Windows Store.
  • In certain cases, the colors in some apps may appear off. For example – the titlebar in the Outlook Mail app is orange.
  • There might be some cases where notifications in Action Center appear blank.

That being said build 10149 definitely feels much more stable and even a bit more fluid compared to previous iterations. Let us know in the comments how the upgrade is faring for you and whether you’ve run into any of these problems.
