Here is a video demo comparing the beta Build 14322 with the current Windows 10 Mobile 10586.218
These new features (and more that are coming) will be released to the general public in July 2016, but you can update to this beta build by installing the Windows Insider app and enrolling in the Fast Ring.
Be warned though, when you install the beta builds, it comes with bugs/issues, so it is not advisable to use it as your daily device. It's recommended you get a secondary phone to test these builds on.
