Earlier in May, Microsoft revealed that its digital assistant Cortana would be coming to Android and iOS, however, a beta of Cortana for Android has been leaked courtesy of Finnish site SuomiMobiili and is already being reuploaded to repositories like APKMirror.
Microsoft believes the leak was through the Windows Insider Program where they ar testing the Cortana for Android beta with a limited number of users in the U.S. and China.
This leak isn’t just a bunch of screenshots: it’s the actual .APK file, which means anyone with an Android device can install it by simply disabling the security setting for sideloading apps.
Cortana for Android requires a Microsoft account. This way, Microsoft wants to ensure Cortana’s personalizations are available to you regardless of what platform you’re using.
