Cortana gets a major redesign and a few new features on Android
First off, Cortana users will notice the settings page has been redesigned to allow for easier management of the assistant. The most visible change is the new hamburger menu that replaces the bottom navigation bar.
Among the new features implemented, the developers mention the option to make hands-free calls and texts. Users will now have quick hands-on control of their reminders. Everything has been made easier to reach, as most options are now just one or two taps away.
Cortana 2.9.0 seems like a major improvement over the previous versions of the app. Keep in mind though that Cortana with Microsoft Band 2 is no longer supported in this version of the Android app.
