Microsoft today released Windows 10 Mobile Insider Preview build 15237 to the Fast ring, the first since 15235 was released a week ago. Interestingly, 15235 actually contained a new feature, a first since the Creators Update was made publicly available.
This is because builds for phones aren"t coming from the Redstone 3 Development Branch like PC builds are. Windows 10 Mobile was split off into "feature2", a new branch that Microsoft has no plans to take it off of before the Fall Creators Update.
Unfortunately, 15237 doesn"t follow in the footsteps of its immediate predecessor, and there are no new features listed. There is, however, a long list of fixes, improvements, and known issues. Here"s what got fixed and improved:
We made some improvements to the Field Medic Store app, where we fixed an issue with collecting Watson crash data, enabled spell checking when editing a report, and updated the PowerOn/PowerOff profiles to include additional battery info.
We fixed an issue where the screen would occasionally flash black after launching or rotating the Camera app.
We fixed an issue with the HP Elite X3 reporting that the SD card had been removed from the device when it had not.
We fixed an issue with Continuum where, after the attached monitor is unplugged, occasionally the mobile LCD does not power off and the mobile battery could be drained.
We fixed an issue with the Windows inbox NFC driver where occasionally the wrong card type data was reported.
We improved the Cortana resume-from-suspend behavior to enable a Cortana skill to be authenticated before the user interacts with the skill.
We fixed an issue with the behavior of the hardware search button in countries where Cortana is not available. In this case, the OEM provides the search app or URI.
These are the known issues:
There is a problem with the HP Elite X3 with wired docks where the portrait orientation setting is lost when the external display is disconnected and reconnected. A workaround for this is to reboot the phone after tapping the “OK” button instead of disconnecting and reconnecting. This workaround must be performed every time you connect to an external display you want to use with Continuum in portrait orientation.
If you have apps saved to your SD card, you may see error 8007000B when trying to update those apps. As a workaround, you can move these apps to internal memory, update them, and then move them back to your SD card. Thank you to all the Insiders who reported this to us!
When installing or updating a Windows Store app, you may see error 80070057. As a workaround, you can get the latest app by uninstalling the older version of the app from your device and reinstall latest version from Store.
While we recommend reading through the known issues before installing any Insider Preview, none of these seem like deal-breakers. All of them list workarounds.
To install build 15237, head over to Settings -> Update & security -> Windows Update -> Check for updates. If you"re not on the Fast ring yet, go to the Windows Insider Program tab and tap "Get started".
