There is no denying that the upcoming Android M is one of the most anticipated releases of 2015. Avid users of Google's Android operating system have been waiting patiently for news regarding its features and launch. While there haven't been a lot of verifiable reports surrounding the release date for Google's newest offering, there are some speculations about when Android M will be available for download.

Android M, which was previewed at the recently concluded I / O last month, is Google's eleventh mobile operating system itineration after Android Lollipop. During its unveiling at the event, Android fans were shown some exciting features of Android's newest installment.

Most of Android M's features that were confirmed during the event are related to the overall security and functionality of Android phones.

All devices running on Android M will not only need individual permissions for applications to access certain information like microphone and camera, but also integrate a fingerprint recognition software to safeguard the identity of the user while making purchases from Play Store and Android Play.

Android M will also bring a new power management scheme that automatically detects whether or not the user is actively using the phone and adjust the battery consumption accordingly.

There is no confirmation about Android M's release date, though rumors suggest that the operating system could be released earlier than expected.

A recent article published by GeekSnack.com has hinted that the upcoming Nexus phone will ship with Android M pre-installed.

"Our source did confirm that at least the joint launch of the new Nexus and Android M is a sure thing," said the report.

Nexus 5 (2015) is slated to be released by October or November this year. With just a few months left for the launch of Nexus 5 (2015), Android M finally seems to be within reach, if the report is to be believed.
