Although Microsoft always encourages their users to try out its pre-release software with all cautions. And while it makes sense for some Windows users, we’re here to tell you that now is not the right time to install Windows 10 Technical Preview on your Lumia device.

Yesterday, Microsoft rolled out its first preliminary build of Windows 10 for phones. The update, which was previewed back in January at a press event, delivers a suite of big time features to Windows Insiders including customizable Start screen with support for full background image and two more tile sizes (an extra-large squared size and a taller one), new Settings menu, Action Center with more quick actions and support for one-swipe away and expandable notifications, improved keyboard with precision pointing stick, new File Explorer app and more.

The update isn’t essentials and but an update that many Windows Phone users have installed already. Personally, I have installed Windows 10 on a couple of currently supported Lumia devices and spent a lot of time with the update on the Lumia 730, which I bought four months ago when it first arrives shelves.

There are a few reasons for being furious about it. First, I can’t imagine “Life Without Windows” – pretty overrated and cliché line – and second, I wanted the features, partially because it’s my job keep Windows users informed.

What features are missing in Windows 10 Technical Preview compared to Windows Phone 8.1?

  • Messaging is currently missing a number of features including dual-SIM support, search, message drafts, sharing voice notes and ringtones, Bi-Di language support, international assisted dialing, spam filter, viewing all group recipients, reminders and quiet hours through Cortana, multiple attachments, and GSM support.
  • In the current preview build, Cortana is only available in English (United States) for phones. In other regions, your phone’s search button will give you the standard search experience.
  • The Rooms feature is not available in the preview. You won’t be able to see your chat history or send or receive any new chats.
  • The Phone app doesn’t have Dual SIM support or spam filtering in the preview. The dialer also appears kinky with smaller buttons.
  • Accessibility features are still being developed for Windows 10, so they aren’t fully functional in Technical Preview.
  • However, Settings menu looks a lot like Settings app on your desktop, but things are still under development. The current build offers a bizarre navigation to old settings.
  • The soft keys often don’t respond as well as you can’t toggle the visibility of the navigation bar.
  • Moreover, you may get jammed with your favorite apps on the preview as things have yet to be finalized for users and developers as well.

Additionally, Microsoft has also published a list of known issues and their workarounds that you should know about this build. Although, the installation process was pretty well on the Lumia 730 and took about 30 minutes to complete. There are new features in the current build, but some bugs and kinks outweigh the charm of Windows 10 as it has a lot of rough edges that will be refined by the time.

Besides, I’m not alone either. I’ve heard from a number of other Windows Insiders had to rollback to Windows Phone 8.1. So don’t get stuck with new features of Windows 10 with a tons of UI glitches that make using your phones annoying.

My recommendation is to wait for the next preview build of Windows 10 for phones to arrive via slow channel only or install it on testing phones only. There’s a good chance that it will iron out some of the edges that many of early adopters are experiencing in Windows 10 right now. If you’ve waited this long, what’s another few weeks? I think it’s worth the wait.

If you have installed the preview and using it, how’s your experience with new features of Windows 10 for phones (build 9941)? Share your thoughts in the comments.


    • Hi Ravi,
      I faced the same issue though Lumia 830 has no problem with background image option. As I said earlier, things will get refined by the time, and certainly, this is not the right time for everyone.

  1. Hi Ramesh,
    Several members of my family purchased Lumia 1020 Windows phones. After the 8.1 update rolled out some months ago we all started having problems with the phones going into Airplane mode unexpectedly. The only workaround is to reboot the phone. Have you heard of this problem and is there an update or patch to fix it? Thanks
