It's been about a month since Microsoft last updated the Windows 10 Mobile Insider Preview. A new build is now available on the Fast ring, bringing it to number 10536.1004. As usual, the build offers a bunch of functional improvements (such as new voice input languages and one-handed mode support for all phones regardless of size), fixes for things broken in older builds (such as mobile hotspot functionality), and new bugs of its own (especially for the Lumia 1020; read Microsoft's blog for all the details). The new Photos app is both hamburgerless and exposes the folder structure on SD media. The new Windows 10 Photos app was updated a couple of weeks ago, and an even newer version is included with the new operating system build.
