Build 10149 Installation experience, a must-read info & known issues

Build 10149 installWindows 10 Mobile Build 10149 is here and if you are in Insider Fast ring you will be able to install the update even if you are on Build 10080 or Build 10136. But before you tap on “check for updates”, you need to know these two things.

  • You need to go to Windows Insider app and reselect Insider Fast ring and then check for update. In case you are new to Windows 10 Mobile preview you need to follow our tutorial for updating to Windows 10 for Phones.
  • Post-update migration bug (Must read info) :
    • Official: The post-upgrade migration status screen is still missing after upgrading to this build which normally shows you the progress of the post-upgrade migration. After upgrading, the Lock screen will appear frozen without the date and time for up to 10 minutes. Please be patient and let it sit – eventually the date and time will appear and it will allow you to unlock your phone. If you get impatient and restart or mess with locking/unlocking your phone, you’ll wind up in a funky state – so just relax and let it do its thing.
    • Our experience: The Lock screen didn’t freeze for us but as you can see in the third screen above for around 10 minutes migration happened in background without any prompt, as the “post-upgrade migration status screen is still missing”. So within those 10-15 minutes, if you tap on apps on start screen you may see the message “app can’t be opened. an update may be available in the store”. Sit tight and check after 10 minutes and it should be back.

Installation experience:

The update takes around 30-35 minutes in getting downloaded over a good connection. The update is around 500-800 MB in size. So check whether you have up to 1 GB free on your device and your device should have battery charge of more than 40% for update to take place. Installation and data migration takes another 40-55 minutes, so a bit of patience is needed. There will be no “post-upgrade migration status screen” as informed by Microsoft. It went quite smoothly for my Lumia 640 XL and Lumia 1020, though you need to read the super-important info above, in case you see any issue with your lock-screen or start screen post completion of upgrade.

Build 10149 known issues:

  • 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.

    On this build, I realised the Photos app has no setting. Now it will display photos from OneDrive automatically – I can’t disable it.

    • Kamal

      It does have setting right at the bottom of the hamburger menu.

      • Gavin

        You are absolutely correct. I can’t see it because it’s shadowed by the on-screen navigation bar. Thank you!

  • Emin Aliev
