Today Microsoft has published a new Windows 10 Mobile Build with the number 10512. Between the last build 10166 and the new one there is not only a big step regarding build numbers but as well the mobile version has made a big step closer to its publication in the coming months.
Microsoft has concentrated on fixing bugs and improving the speed of its mobile OS in this new build. Therefor there are just a few new features in this build. Basically the update makes the preview better for the everyday use. I think the user experience will be much better than in the last builds. Of course there are some bugs left like mobile hotspot doesn’t work. Microsoft has published an overview of all bugs here: http://blogs.windows.com/bloggingwindows/2015/08/12/announcing-windows-10-mobile-insider-preview-build10512/
Microsoft wanted to publish a new build earlier but there was a bug which has prevented the publication.
For all who are interested in joining the Windows 10 Mobile Insider Program on their phone here the instructions. You need to download the Windows Insider App from the store. In the app you have to log in and choose fast ring. After that the update to the Windows 10 Mobile preview should be shown in the settings. But don’t forget that this is a preview so maybe there are bugs or other problems. A preview should be used for testing and not as a productivity system. So I would recommend to not use the preview on your main device because the preview could make it unusable.
I will write an article about the new build with more details in the next days.
