Windows 10 for PCs is already here, but users on smartphones are still waiting on the new OS. Although it's not ready to go onto handsets yet, Microsoft is deep into development, pushing out build 10512.
It has taken Microsoft an unusually long time to get this latest build out to users. This is likely primarily because of the need to focus on the PC release of the OS over the last couple of weeks. During that time, however, Microsoft has managed to make considerable changes to the mobile build.
The build features performance and stability improvements, layout changes, improved writing algorithms, language improvements, and other bug fixes. A few new features have also been added, such as the ability to use a picture from the Photos app as the background image for your lock screen.
A few problems persist in this build, though. For example, mobile hotspot functions are currently not working, and various applications are experiencing problems, but as this is a project build, that is to be expected to an extent. Most of these bugs are related to the Windows Store and programs that connect to it, such as Groove and Movies & TV. Users who want to try the new build should tread carefully while using these applications.

Now that Windows 10 is out on the PC, Microsoft should be able to shift more of its resources into finalizing the mobile version of the OS.
