Screenshots surface of Windows 10 Mobile build 10158 running on the Microsoft Lumia 830
According to the source of the screenshots, this build will not be available as a preview for Insiders. The next build available as a preview will be in the 1016x range.
As for the current 10158 build, the Beta tag is removed from the Windows Store and the whole OS runs smoother than it did with the previous build. A new version of wallet is included, and there are new resolution options for video recording. The new version of the Microsoft Edge browser (version 20.10158.0.0) is included. The other changes cited by the source are ones that we've already seen on the video of the emulator.
The excitement is building for Windows Phone 8.1 users with the release of each new build. Despite all of this hard work, rumors persist that Microsoft is taking a hard look at using Android in some capacity. After all, the company does own some major patents related to the rival OS.
