Microsoft last released Windows 10 Mobile Build 10586.107  to Windows Insiders in Fast and Slow rings and finally to those non-insiders using a Lumia 550, 650, 950, 950 XL. We shared our first impressions and hands-on demo of the build on Lumia 950 XL, Lumia 640 XL and Lumia 525. Now we hear that the Build 10586.122 under internal testing may be the next build to be pushed to Insiders with older Lumias.

Screenshot of the build has also been posted on Twitter and the leakster hints it to arrive soon.

Build 10586.122 has been also seen on BuildFeed and we hear that Microsoft may be rather working to push this build to Insiders in coming week. This build was compiled on February 22nd and testing for this build has been yielding good results so far. So, if everything remains promising it may go out to Insiders on Fast Ring soon.
