Here are the fixes, improvements, and known issues in Windows 10 Mobile build 15204

Microsoft released its first Redstone 3 build for phones today, build 15204, which is a preview for the next feature update of Windows 10. It came alongside 16176 for PCs, which only added a feature for the Windows Subsystem for Linux and some OneCore improvements.

Most notably, 15204 removes support for older devices, but there are also some fixes, improvements, and known issues. Here's what got fixed and improved:

  • We have added a new privacy page to the Windows 10 Mobile OOBE experience that allows you to quickly and effectively make common privacy changes while setting up the device. You can read more about our Windows 10 privacy journey here.

  • We fixed the issue where the keyboard would sometimes not appear when a text input field is selected in Microsoft Edge.

And here are the known issues:

  • For Insiders who have upgraded from a prior 150xx build to this build, the “Add Bluetooth or other devices” Settings page and the Connect UX page may fail to open.
  • Some users are reporting that pages are constantly reloading or refreshing, especially while they are in the middle of scrolling them in Microsoft Edge. We’re investigating.
  • There is an issue with Microsoft Edge where you might get into a bad state after opening a new Microsoft Edge windows and screen off with the JIT process suspended.
  • Continuum will stop working when HP Elite X3 case is closed.
  • Continuum hangs or renders incorrectly after disconnecting on devices like the Lumia 950.
  • The device screen might stay black when disconnecting from a Continuum dock after screen has timed out normally.

As there are no new front-facing features in this build, you might want to skip over it. Given the known issues, it's risk with no reward.

Of course, the vast majority of Windows phones that are in use can't get it anyway. If you're using a Lumia, it needs to be an x40 or x50 device, and then there are some third-party handsets that are supported. Luckily, if you really still want the Creators Update, build 15063 is still available in the Fast ring for older devices.

If you're in the Fast ring, you can get the latest build by heading over to Settings -> Update & security -> Phone update -> Check for updates. If not, go to the Windows Insider Program tab and tap 'Get started'.
