Windows 10 Mobile fourth preview build, the Build 10080 is already here and while we are in the process of posting the screenshots and installation experience, here is something interesting that we could note. It seems with the latest build Microsoft has managed to get some serious jump in the HTML5 scores of both the browsers: Spartan and Internet explorer. Surprisingly Internet Explorer has score of 390 that is one point higher than that of Spartan scoring 389.
Last we tested the Internet explorer on first preview build of Windows 10 Mobile had a score of 360. So, it is quite an improvement to touch 390. Hope Microsoft keeps it improving.
