From the Windows blog: (with items that have bugging AAWP readers in bold)
Today we are excited to release Windows 10 Insider Preview Build 16257 for PC to Windows Insiders in the Fast ring and also in Skip Ahead! We are also releasing Windows 10 Mobile Insider Preview Build 15237 to Insiders in the Fast ring.
General changes, improvements, and fixes for Mobile
- 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.
Known issues for Mobile
- 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.
So still issues for Elite x3 owners then, though with HP pushing hard I'm sure the issues will be solved before formal release of this OS branch.
I should emphasise that there are always additional small under-the-hood OneCore and UAP improvements and fixes which are too low-level to report in the Microsoft post.
See my feature on upgrade paths for the various classes of existing W10M handsets and the wider grid covering older devices, even though most of these won't be able to take advantage of this (RS2+), even with the Insider programme.
Anyone with an existing phone that's officially deemed Windows 10 Mobile CU-compatible by Microsoft can join in the fun - in theory. In each case:
- Head into Settings/Update & Security/Windows Insider Programme.
- Join the Insiders programme and choose the 'Fast' level in the pick list.
- Within a few hours your phone should be seeing the build mentioned above and you'll be running the Creators Update and beyond...
Note that the popular Lumia 930 and 1520 haven't yet been 'provisioned' for this branch of Windows 10 Mobile. I tried - setting the Insider level to 'Fast' doesn't show up any of the recent 152xx builds. Do ping me if this changes, but I'm prepared at this point to say that these 2014/2015 phones may have reached their plateau on the Creators Update Release Preview ring, which will see critical updates through 2017 and then... no more after that.
