As with all preview builds, the latest to hit Windows 10 Mobile contains its share of bug fixes, as well as some lingering issues. In Windows 10 Mobile build 14342, Fast ring Insiders can look forward to quite the laundry list of fixes, along with just a few issues.

What's been fixed and what's broken in Windows 10 Mobile build 14342

Here's the breakdown of what's new and what's still broken in Windows 10 Mobile build 14342. From Microsoft:

What's fixed

  • We fixed an issue causing installation of mobile builds to fail with Error 80070002.
  • Language and Speech Packs should download without any errors.
  • We have 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.
  • We 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.
  • We 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.
  • We 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".
  • We fixed an issue where some apps, including Tweetium, would crash on launch.
  • We fixed an issue where Action Center's context menus would appear in the wrong orientation if the app underneath was in landscape mode.
  • We 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.
  • We 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.
  • We fixed an issue where Glance wouldn't be displayed when hovering hand over proximity sensor.
  • We fixed an issue where multiple UWPs might start crashing on launch after getting stuck on their splash screen.

Known Issues

  • We are investigating issues with some Dual-SIM devices.
  • Feedback Hub is not localized and the UI will be in English (U.S.) only, even with language packs installed.
  • We have reduced the number of instances where boxes are seen when entering emoji. You may still see them in some text fields – we're working on it!
  • 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.

Microsoft also notes that this build has removed the Wi-Fi Sense feature that let you share Wi-Fi networks with your contacts. The same move was taken for this build on PC with build 14342 as well. However, if enabled, Wi-Fi Sense will still connect you to Wi-Fi hotspots it knows about. From Microsoft:

The engineering effort to keep this working great, combined with low demand for the feature made it not worthwhile to keep investing in it. Wi-Fi Sense, if enabled, will continue to get you connected to open Wi-Fi hotspots that it knows about through crowdsourcing.
