The last Windows 10 Mobile preview version for Windows Insiders was build 10536 that was released in mid-September. Now, some new screenshots of a more recent internal build have been leaked, showing some small but interesting new features compared to build 10536.
According to WinBeta, the new version doesn't appear to have a specific build number. However, the leaked screenshots do show that this build will allow users to change the size of text on the screen, similar to how PC users can change the DPI on the desktop. This new feature will also allow for more columns to be shown on the Start screen if the display has a high enough resolution.
The new build also includes some extra options in Developer Mode, In addition, WinBeta reports this build has some bug fixes and performance improvements as well.
There's no word on when Microsoft will release a new Windows 10 Mobile build, but Windows Insider head Gabriel Aul has already stated no new builds will be released before the company's big press event in New York City on October 6.
