Microsoft today released the newest version of Windows 10 mobile build 10149 for Windows Insiders. Here’s a look at what’s new in this most recent build.

Windows 10 Mobile Build 10149

Microsoft announced the rollout of this latest build today and it’s worth noting with the previous version, build 10136, you had to reset your phone to Windows 8.1. If you chose not to do that and stuck with build 10080, you don’t need to reset your phone, and you’ll get this update directly.

Another important note is the post-upgrade migration status screen is still missing after upgrading, which is a known bug. So, after the upgrade, the Lock screen will appear frozen without the date and time for up to 10 minutes.

Do absolutely nothing and let it sit, and don’t touch the phone at all. If you try to restart it or anything, you’re going to mess up the update and have to start all over again…which won’t be fun.

In my update experience this evening, it took well over an hour for the update to download and install on my Lumia 635, but I would be interested in hearing from any of you with different models of Windows Phone on how the update went.

Windows Mobile Build 10149

I’ve only been able to use this build for a few hours, but so far, it has been a fun experience. I was much happier with the previous build, and this latest one makes things better and shows that the mobile version of Windows 10 is starting to come together.

As always, there are known issues with this build. While we are getting closer to the Windows 10 for PCs official release date of July 29th, Windows 10 Mobile will ready after that, so remember we’re still in beta. Microsoft posted some of the known issues:

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.

    Installed the new update on my two year old Lumia 920. Running fine for the most part. I do have eight apps that will not update and function. When trying to update these apps I receive error code 0x80070003 and can’t seem to locate any useful info on this error. Two of these apps I really miss are the Nokia HERE Maps and Drive+ that use regularly. Hope they get these apps working. I did notice a real improvement in how the Outlook app functions in this build over build 10136 that was previously on this phone. I do have the orange bar at the top as mentioned in the article but no big deal for now as I know it will be fixed. So far running the new build all day today and I am happy with the results. We’ll have to see how it continues to perform.

      I agree with you on Outlook, it still needs some work, but it’s definitely coming along quite nicely. I haven’t tired HERE or Drive+ yet, and haven’t gotten any errors yet on my Lumia 635. Apps do have a tendency to crash out of nowhere though.

      Another thing I have noticed since build 10136, and I am wondering if anyone else has noticed this:

      I seem to have to press the tiles and messages harder — apply more pressure to them than I used to.

        I have used the new build for around a day and have not experienced any crashes at all. I do experience delays when touching some of the icons, but not any real difference in the sensitivity of my screen from Windows 8.1 Update 1. I do find myself doing the three button reboot a few times due unresponsiveness from the phone and all goes back to “normal” after this. I am still quite pleased with this new build so far.

    The update took close to one hour from start to finish. This is probably the best update so far. It looks and feels like an end product. I did have a couple of issues on my Htc one M8. A day after I updated none of the apps worked. I restarted it and that was solved. Then the beta store wouldn’t work. I opened and closed the regular store app and the beta app worked still a little quirky but looks great. The response is fast and the apps have a sharp look to them. Can’t wait for the final update.

      I had the same problem after about two days and I rolled my phone back to Windows Mobile 8.1 and will wait for a few more versions before trying it again. I couldn’t find a solution to the battery drain with build 10149 even using the Battery Saver app which I don’t believe was working as designed. That may have contributed to the problem.

    I also recently upgraded my lumia 1520 to windows 10. It seems fine except that there is a message of an available update which when I try to download it hangs on 0% in downloading updates.
    And each time i load airtime it finishes before i can go to my social networks or before i can make a call. This has been happening for the past week.
    How can i make this update to download? i am really stuck

      Did you try the three fingered reset (Volume Down, Power and Camera buttons depressed simultaneously until phone boots)? I had to do my 920 twice before Windows 10 settled in and ran as expected.

        I have tried that for a number of times but it’s not working. I’m even thinking of reverting to windows 8.1. Is it possible? Or is there another way of getting this download done?
