What's new in Windows 10 Mobile Insider Preview build 10549




Improvements to Cortana: Cortana now works for Insiders in Japan and in English for Insiders in Australia and Canada. For more information on new languages in Cortana.
Messaging app improvements: The Messaging app now has a text box that can be expanded as you enter text. Previously, the text box had 2-3 lines which made it really hard to see what you were typing. 
Diverse emoji: With this build, we are adding support for Unicode’s diversity emoji’s. Consistent with Unicode’s vision, we’re excited to offer people all over the world with emoji that reflect more human diversity. We added this capability to the PC with Build 10547 and now we’re extending to mobile. Check out our new diverse emoji and let us know what you think.
