The speculation is now over, Android M has been revealed as Android Marshmallow.
Google revealed the details of Android M at Google I/O in May and ZDNet's Kevin Tofel posted all you need to know about this new version of the operating system. Key improvements include an updated user interface, advances in sleep mode battery management, Android Pay support, volume control changes, and much more.
Now that we have details on Android Marshmallow, and the name, it's time for Google to reveal the next Nexus device, or two. Kevin also just posted the latest LG Nexus 5 leak with a back camera module reminiscient of the HTC One X. That leaked image also shows a rear fingerprint scanner below the camera.
Developers have had the chance to test out early versions of Android M with the second release appearing in July. Permission access is a major component of Android Marshmallow.
