In a forum post in a user (claimed Windows Pone tester) posted the rumored three button functions of Windows Phone 8.1.

They are

  • Long Start = CORTANA (voice assistant)
  • Double Start = What is going on area?
  • Double Back = ends current app

The first one, Long Start, is already how TellMe works and it makes sense that Cortana would act in that manner as well. We’re unclear what the Double Start is referring to and the third change, double Back, sounds like an easy way to close out apps, something that we know is coming in GDR3
