If you’re into the Windows Phone 8.1 dev preview then Microsoft has something for you as the company released Build 12400 of the mobile OS. We’re yet to determine what updates and features that came with the update but we are certain that this build are mostly bug fixes, stability enhancements and optimizations.

The update weighs around 21 MB in size and is available those who joined the free development preview program.
