The latest Windows 10 Mobile preview build came out a couple of weeks ago, and Microsoft is currently hard at work to release Windows 10 Mobile build 10134 as soon as possible.

Microsoft promised to speed up the release of Windows 10 Mobile Technical Preview builds, but due to some problems that couldn’t be fixed on time, it had to postpone things. Still, it seems that the company is continuously in the process of experimenting with different versions.

For example, a Lumia 830 phone running build version 10.0.10127 was spotted in a testing video posted on the Chinese video streaming website Youku.

Luckily, the video is accompanied by English subtitles, so we are able to tell you that the purpose of build 10.1.10127 is mainly to squash a lot of bugs.

As we’re walked through the features, we can see that the Lumia 830 now supports horizontal screen operation.

Moving on, we’re told that it’s possible to set the same exact interface as with a co-existing Windows 10 PC, so the classification has been revised accordingly.

Naturally, there are a few differences compared to Windows 10 Mobile build 10080, which brought to the table a lot of new features. Some of them have to do with certain settings being moved into different menus under different names.

It’s pretty well known that build 10080 also brought a lot of bugs and issues into the equation, an aspect which put a damper on the whole user experience, and it appears the new 10127 version bears some incongruities of its own. The Chinese tester says he has identified a new scrolling (the subtitles call it “rolling”) screen problem.

But let’s talk more about the positive aspects. First of all, you can now adjust the system’s font size from 100% to a maximum of 200%.

Moreover, with this build “Project Spartan” is still present and not the re-named “Edge.” Also, we’re given a view in-browser with magnified fonts, advanced settings and Clearing private data options are visible, and the icon of the Maps app has a different look now.

The new version can be downloaded from the App Store in beta state, but it’s not available for phones running the 10080 build.

From within the app, users can no print maps, but loading them is pretty slow. Moving on to the camera, where the phone operates with Lumia camera beta, we’re told that when recording video, one can manually adjust the focus, white balance and brightness.
