As you all know (or may not know) the first build for Windows phone 10 OS was released more than 50 days ago and it was limited to just a handful of Lumia models; the Lumia 830, 730 and the 63x series, that build was buggy and as unstable as they come, Here is a video reminder of how buggy that build was...
Granted it was the first build (pre-Alpha build), it wasn't greeted with not as much enthusiasm as the Windows 10 for desktop.
But this next build due Friday will supported an expanded list of Lumia phones including the Lumia 1020, 1520 and even the 920 along with pretty much every other Lumia model in the market today, except the Lumia Icon/930 model (for reasons unknown).
This next build's rumoured to bring with it a revamped contact list, new Outlook mail and calendar apps, the new Project Spartan browser, new messaging app, among a host of new features.
This is might be the build we have been waiting for as Microsoft is looking to polish the Windows phone 10 OS Build quick as the Microsoft Build event is fast approaching (Apr. 29th) and everything has to be in decent shape before developers can take a stab at it officially.
To get your hands on the upcoming build, be sure to have a Lumia phone (see list of compatible Lumia phones) and have the Windows Insider app installed...
