Last week, Microsoft rolled out Windows 10 Mobile Insider Preview build 15205 to the Fast ring. 15205 was the second build to emerge from the new 'feature2' development branch, after Microsoft split development of its Mobile OS from the main Redstone 3 branch, which is currently available to PCs.
Today, Microsoft released Windows 10 Mobile build 15207 to the Fast ring, but there's not a great deal to get excited about. Windows Insider Program chief Dona Sarkar described it as "exactly the same as Build 15205 released last week but with one additional fix we would like extra coverage on from Insiders":
We have added a privacy page to the Windows 10 Mobile OOBE and upgrade experiences that allows you to quickly and effectively make common privacy changes while setting up the device. However, Insiders have reported that their device would crash or reboot shortly after unlocking their device for the first time after the upgrade if their device did not have a password configured to unlock the device. After updating to Build 15207, you will see this privacy page one more time – but should no longer experience a crash or reboot.
As with the previous feature2 releases, build 15207 is only available to the 13 Windows 10 Mobile handsets that Microsoft is now supporting on the Insider Program. The same 13 devices will be the only ones eligible to upgrade to the new Windows 10 Mobile Creators Update, which will begin rolling out tomorrow.
