Now, it seems Build 14921 may be the next build coming to Fast Ring. Dependable build forecaster “Core Insider Program” has hinted about Build 14921 as the next probable build.

Windows 10 Mobile Redstone 2 builds till now haven’t brought any major new feature or change. So, hopefully Build 14921 will be the first exciting build. The build has been compiled on September 3 as per its entry on Build feed.
