Windows 10 Mobile

Windows 10 Mobile build 14295 review on Lumia 640 is here. Few days ago Microsoft surprised Windows Insiders by releasing Windows 10 Mobile Build 14295 in fast ring. As reported earlier, Windows 10 Mobile Build 14295 or any Windows Redstone build is available for more devices after Windows 10 Mobile official launched. You can find the list of devices that supports Windows 10 Mobile Build 14295 or Windows Redstone Build by clicking here.

Windows 10 Mobile Build 14295 is very minor update from Windows 10 Mobile Build 14291. It just contains bugs fixes and new known issues, bah. There were also some reports claiming Windows 10 Mobile Build 14295 is not available for all selected devices at once. However, now its seems Windows 10 Mobile Build 14295 can be downloaded on any selected devices which is running on Windows 10 Mobile (official) or build 14291.


Windows 10 Mobile Build 14295

Windows 10 Mobile Build 14295 on Lumia 640 installed after lots of hiccups. We faced many problems while installing this new build on our Lumia 640. As stated in older reviews, we performed a hack to get Windows 10 Mobile Redstone build for Lumia 640 or any Lumia. But, it seems Microsoft recently patched that flaw which allowed us to get Windows 10 Mobile Redstone builds on unsupported Lumias. However, if you performed a hack to get Windows 10 Mobile Redstone builds on your phone. We suggest you to revert your phone back to Windows Phone 8.1 and then upgrade it to Windows Redstone on your supported devices.

On other the downloading took massive 7 hours! Like previous Windows 10 Mobile Builds, again our device was losing connection to Windows Update server. Microsoft should work on fixing such connection issues as there are many users who are upgrading their phones to new Windows 10 Mobile builds at same time. However, this time preparing to install step took around 30 minutes for us which also longer than expected.

After, downloading and preparation, our phone booted into spinning gears and it took around 20 minutes to enter into migrating process. The migration process completed in just 10 minutes, which is quite faster but normal when compared with last Windows Redstone Builds. After, migration steps finishes, Lumia 640’s start screen stuck at loading screen for some minutes. Most of the apps were not available, either not opening. We restarted our phone twice or thrice to get all apps back. But, in this migration process we lots few apps which were installed in external memory.



I don’t understand, why Microsoft released Windows 10 Mobile Build 14295 to Windows Insiders. This build doesn’t comes with any single improvements. In fact, there are new annoying bugs like, while playing YouTube videos on Microsoft Edge in full screen mode the screen started to blink along with action center and navigation bar. There are others bugs like space key in keyboard is still not working sometimes.

And, here are some known issues:

  • After updating to the most recent builds from our Development Branch, a system API failure occurs after the update that causes the Microsoft Band 1 or 2 to have sync issues. To get out of this bad state, you can reset your phone on this build, re-pair your Microsoft Band, and syncing should work again.
  • After upgrading to this build from a previous build from our Development Branch, attempting to connect to a Miracast receiver the connection will fail. There is no workaround for this issue unfortunately on Mobile.
  • The Gadgets app will not detect the Microsoft Display Dock on phones running Windows 10 Mobile Insider Preview builds, and thus cannot update the firmware version. If you have a dock which has already been updated to version 4 then this will not affect you. If you have a dock that has not been updated, then you may experience some minor issues with USB-C stability. You will still be able to use your dock and Continuum.



Windows 10 Mobile Build 14295 performed quite buggy on our Lumia 640. Even, though ow the device is supported officially by Microsoft. On other, UC browser is still not opening on our Lumia 640 as its getting stuck at loading screen followed by force close.

Along with UC Browser, Twitter for Windows 10 Mobile also crashes frequently while DMing anyone. We checked in Windows 10 Mobile Build 10586.164, Twitter was not crashing rapidly like its happening in Windows 10 Mobile Build 14295

  • Windows Store [Fast]
  • Microsoft Edge [Fast]
  • Windows Camera [Fast]
  • People App [Fast]
  • Calendar [Good]
  • Outlook [Fast]
  • Maps [Smooth]
  • Settings Menu [Fast]
  • Messaging [Fast]
  • Twitter [Buggy, crashing, huh!]
  • OneDrive [Smooth]
  • WhatsApp [Good]
  • Facebook [Little fast]
  • Skype [Smooth]
  • OneNote [Fast]
  • Word [Fast]

God bless Microsoft! There are some fixes included in Windows 10 Mobile Build 14295:

  • We fixed the issue where if you reset your phone on Build 14291 and restore your phone from a backup, restore will fail to install apps from your backup’s apps list leaving blank grey titles on Start. You should be able to reset your phone on this build, do a restore from a backup, and have your apps installed and restored appropriately.
  • We fixed an issue where new languages and keyboards were not downloading. However, there is an issue where the “reboot” UX doesn’t appear in the Settings app after downloading a new language or keyboard. You will need to go to Update & security > Phone update and restart your phone manually from there for the new language and keyboard to go into effect.



Windows 10 Mobile Build 14295 experience on Lumia 640 was not very good. But, keeping in mind its a preview build. You can download this build by selecting fast ring Windows Insiders app.

We’re soon going to publish our video review on new mobile build. Do let us know your experience in comments below:

  • Parazels

    Could you show speed of the apps from the article in the announced video? It would be fair. Thanks.

    • Mayank Parmar

      Sure, I will! Your welcome :)

    The new Build 14295 on 640DS is bad. I have a lot of crashes even some of the basic apps won´t work probably, sometimes even outlook is crashing. In some cases I can´t use my phone productive (Outlook crashes). This is the worst insider experience for me. The last builds were smooth, now I have a smartphone with a lot of problems. At first I liked the insider program, now I´m just pissed and it is not that easy to go back to production .164. I get it when they try something new, a new feature and it doesn´t work well, but basics crashing? Really? Every build there is the same game: solving and creating problems and bugs. And the whole OS is just poor, I am missing so much features. But I am not caring anymore, actually I´m looking for an Android device.

    • Mayank Parmar

      I am not facing such issues with my Lumia 640. You can go for hard reset, it may fix some of the issues you are facing currently. Ah, regarding new features! Today is the day! Build 2016 will introduce lots of new features for W10M!

      • Stefan Binder

        Thanks Mayank, but this is not an option for me. I also use my phone for work and i need all my data on the phone and I don´t have the time nor the nerve to save my data and put it back on the phone. The OS is under contruction, it´s not finished, and for me the whole concept isn´t continuously, maybe I am not part of MS´s target group. It was my fault to believe that Win10M must be the gamechanger for Microsoft since they said “mobile first, cloud first”. They can do their conferences and meetings and concepts and announcements, I take a Lumia in the my hand and I don´t think they can win a third place with this OS, there are better options. I know just 3 people who even tried Windows Phone, they changed back yet or will be soon. Android or iOS have their problems too, but still the better options.

        • Mayank Parmar

          I understand. You can use W10M Build 10586.XXX Builds. Its quite stable than Windows Redstone.

          • Ninad Ganore

            10586 is in fast ring?

          • Mayank Parmar

            No. Fast and slow ring are for Windows Redstone. Release preview ring is for 10586.XXX.

  • Ninad Ganore

    By the way that blinking problem is also in any video that we play on the internet(edge) and also in the inbuilt video player, 6tag ,opera,uc browser stopped working .

    • Mayank Parmar

      Hmm, I heard that. However, UC Browser has stopped working for me since first Redstone Build. It stuck at loading screen and the it crashes.

      • Ninad Ganore

        Groove music also crashes regularly (stopping music)

        • Mayank Parmar

          That’s odd. Go for a hard reset.

      • UC Browser has been broken since I’ve been on 10. I mean, I can browse, but I can’t sign into any sites, which sort of makes it mostly useless.

        • Mayank Parmar

          They don’t even planning for Windows 10 Mobile app. We have to live with *buggy* Microsoft Edge :/

  • And they gave it to us slow ring people three days later. I guess they figured, “So many bug reports we could never read. Fuck it. Let’s give it to everybody then.”

    • Mayank Parmar

      LOL :D
