Windows 10 Mobile Insider Preview Build 14342 Available for Download

UPDATED on May 16, 2016: Release of Windows 10 Insider Preview build 14342 for mobiles.

NOTE: These are testing builds of Windows 10 Mobile Insider Preview officially released by Microsoft. These builds are under development and testing phase and may contain bugs, issues and other problems. They may also make your phone not bootable in some rare situations. So install and use these builds at your own risk. If something goes wrong, you can try to repair your phone by restoring default firmware using Windows Phone Recovery Tool.

If you are using Windows 10 Insider Preview (previously known as Technical Preview) for mobile phones, here is a good news for you. Microsoft has released a new build 14342 of Windows 10 Insider Preview for mobile phones. This build comes with fixes for many issues which we'll discuss later in this topic.


What's New in This Build?

Following are the new features and changes in this build:

  • Support for 3 new devices: Lumia Icon, BLU Win HD LTE x150e and BLU Win JR x130e
  • Wi-Fi Sense feature removed due to low usage and low demand
  • You can now swipe from anywhere on a web page to go back to the previous page in Microsoft Edge
  • New page in Settings -> System -> Apps for websites which is currently not functional
  • Improvements to Feedback Hub

What's Fixed in This Build?

Following are a few things which have been fixed in this build:

  • Fixed an issue causing installation of mobile builds to fail with Error 80070002.
  • Language and Speech Packs should download without any errors.
  • Fixed the issue causing DRM-protected content from services like Groove Music, Microsoft Movies & TV, Netflix, Amazon Instant Video or Hulu to fail on playback with 0x8004C029 or 0x8004C503 errors.
  • Fixed the issue where some users with some non-English keyboards were not able to enter letters such as w, y, and a when typing into the address bar of the Edge browser.
  • Fixed the issue causing your phone to lock up and reboot when it receives a notification from an app that has "Keep notifications private on the lock screen" turned on under Settings -> System -> Notifications & actions.
  • Increased font size and improved spacing of the data migration page after receiving an update.
  • Polished icons used to identify pages in the Settings app. In particular, updated battery icon to be more consistent with the weight of the other icons.
  • Improved performance when retrieving updated GPS coordinates while driving.
  • Goodbye message on shutdown will now remain visible until the last moment, to make it easier to determine when your device is off.
  • Polished the look of media controls on the Lock screen. When you press one of the media control buttons, it appears "Pressed".
  • Fixed an issue where some apps, including Tweetium, would crash on launch.
  • Fixed an issue where Action Center's context menus would appear in the wrong orientation if the app underneath was in landscape mode.
  • Fixed an issue where Lumia 435, 532, 535 and 540 would fail to record video, as well as an issue where advanced camera settings were not preserved when taking a photo with the Lumia 435, resulting in the photo being taken with default settings instead.
  • Fixed an issue where the same device might be listed multiple times under Connect.
  • Fixed an issue where quickly pressing the power button twice when Windows Hello is enabled could result in the display appearing stuck off.
  • Fixed the issue where Groove Music might show an error saying "Can't play - Another app is controlling your sound right now".
  • When delayed lock is setup, Windows Hello will now say "Swipe up to dismiss the lock screen", rather than looking for your iris.
  • Fixed an issue where Glance wouldn't be displayed when hovering hand over proximity sensor.
  • Fixed an issue where multiple UWPs might start crashing on launch after getting stuck on their splash screen.

Known Issues in This Build

Following are the known issues with their workarounds in this new build:

  • After your device reboots from installing this update, if it gets stuck as the Windows logo - let it sit and be patient. It might appear frozen but its still working in the background. While you wait, it is recommended you plug your phone in and let it charge as well.
  • There are some data issues with some Dual-SIM devices where cellular data doesn't work correctly with a second SIM. Several issues relating to cellular data with Dual-SIM devices have been reported by Insiders with the last two Mobile builds and Microsoft is investigating these reports.
  • Feedback Hub is not localized and the UI will be in English (U.S.) only, even with language packs installed.
  • Microsoft has reduced the number of instances where boxes are seen when entering emoji. You may still see them in some text fields.
  • The Settings app may crash when you are re-arranging Quick Actions under Settings -> System -> Notification & actions. If it does, it could result in one of the Quick Action spots disappearing. If you see this happen, please refrain from changing your Quick Action settings on this build. If you have been impacted by this issue, only a hard reset will revert your Quick Action settings back to default.

  • I don't think 925 is really on the list, as of 17 March. I hope they will add it after.

  • Which build is last for Lumia 630 ?!?

  • Lumia 535 dual sim is not supported for this 14291 and 14295 built by mine one was accidentally updated during mid nite auto update. In this built you need to remove one SIM card in order to get mobile connection and wifi. After few hours of update, this phone was overheated and worst battery life.

    Next day rolled back to Win 8.1 because battery only last for 6 hours and the heat can burn my skin

  • Lumia 730 dual sim - after build 14291 update I have to remove one sim in order to get mobile data connection. With both sim cards in, the phone will freeze when I try to go in Cellular&Sim settings

  • Battery drain is through the roof - Lumia 640.

  • After updating win 10 14295 preview of the Nokia Lumia 730 does not set the alarm volume. nearly the alarm does not ring.
    Another problem is the high battery consumption compared to the previous preview 10,586th Any advice? Thanks
    How can eventually return to the previous preview?

  • 14295.1000 that was the worse build tested on 2016 in my phone there are many issues.
    is is not stable, the system block very often like 2 times a day requiring reboot. battery status doesn't work very well.

    the tools status at up related with the status bar is not working very well. since the last update the screen block when you try to change the status, , enable or disable 3G kill the WP application.

    Doesn't appear the last's sms message.

    many apps just doen't turn on.

    I don't perceive drain the battery.

    write what you speak is working fine.

    take a look if you loose any improvement on build 164 much more stable.

  • after new build update automaticlly connect to wifi option not working in my home i reset my phone for solving this problem..and now also that option not working..and language pack download option also not working....what i do??..plz solve this problems.

  • Dear. all,

    After the last wp10 upgrade my lumia 640 LTE does have a problem with the battery.
    Before the upgrade, i was able to use the Phone 2 days.
    now my battery is empty in 1 day!!!
    And my WiFi can i not disarm, after a while the wifi is going on..

    Please go back to the old settings!!!!

  • microsoft lumia 540 windows 10 build 14327.1000 not working wifi and mobile data and hotspot and data uses after switch off mobile

  • just update my lumia 535 on latest insider build 14327.100 only issues camera not working but using old Lumia camera app will do, double apps. hope this issues will be fixed soon.

  • Hey all you older (the phone, not you) Lumia users with the battery/heat issues... I am right there with ya. Try turning off your GPS radio (i.e., turn off location services) entirely. This *appears* to have settled my unit down, and I was having hella time even getting it to restart or charge because I had let it drain so low and get so hot. Obviously this is not a fix but it might at least get you functioning again long enough to flashback or even live with it while a fix is prepped. Please everybody having this issue log it with Feedback Hub.

  • For my 640XL this build is a serious step back in reliability and energy consuming.
    Almost any memory-demanding app just crashes on startup. This is about skype (always), edge (on heavy sites), facebook (when scrolling down to load more data) etc. I cannot even send a feedback from my phone - the app also crashes.
    Before I could live from 2 to 3 days without charging my phone. With this build I need to charge it TWO TIMES EVERY DAY! Most consuming apps are: lock screen, start and phone.
    For lock-screen I tried to switch all notifications off - but no improvement: it still eats the battery more than any other app.

    If there is no update in the next day or two - I'll have to switch back to Windows 8.1
