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.

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.
