Microsoft is likely on the cusp of unveiling its first Windows 10 phones, which has left more than a few fans wondering why it hasn't posted a fresh preview version of Windows 10 Mobile in a while. Well, wonder no longer -- the company has released an updated preview build that not only fixes a number of key bugs, but introduces a big upgrade to the photo experience. Fire up the Photos app and you'll get a folder view that makes it easier to see what's in OneDrive or your phone's SD card. You can also mark photos as favorites, and navigating your gallery should be faster overall.
