While most Android users are yet to receive Android M on their devices, Google is already ready to roll out its successor, Android N. While the Mountain View tech titan is expected to announce Android N at Google I/O scheduled for May 18, the first screenshot of the next mobile OS have already surfaced online.

The screenshot was spotted in a post about Android Support Library v23.2 on the Android Developer's Blog. The screenshots were related to an unreleased Android version. The website confirmed that the screenshots were of Android N, as they revealed a new left hamburger button in the Bluetooth settings section. This button does not exist on Marshmallow.

The new hamburger button will help open the side drawer, which contains a list of the entire settings sections. Hence, users will not be required to go back to the main settings screen and to choose any section. "It will allow the users to simply open the drawer, tap a new section, and jump to another setting area immediately, the report said.

Although Google has been insisting that developers make the drawer a regular feature in all their apps and not something that can only be accessed from one screen and not from another. However, there is no confirmation whether or not the inclusion of the drawer in Android N would help to make the upcoming mobile OS faster.

Similar to Android 6.0 Marshmallow, it is expected that Google will roll out the new Android N with its upcoming new Nexus devices in the near future. Although the first screenshots of the next mobile OS has already been revealed, it would be too soon to comment on the design changes or changes that Google may have undertaken to develop Android N.

Since the screenshot was taken on a Nexus 5, it can be expected that the new mobile OS will arrive sometime next year, when Google is likely to release its next-gen smartphone. In addition, to the new navigation drawer, Android N will also include features like Split Screen and Multiwindow as well as enhanced tablet and stock stylus support, Tech Times reported. Another noteworthy feature of Android N is that the new mobile OS will use OpenJDK rather than Oracle's Java API.

In addition to Android N, the Mountain View tech titan is also expected to announce a slew of other projects at its upcoming Google I/O, including Project Tango, Project Ara, Android Wear updates, new and improved Google Cars, details regarding Nexus 7 and a monocle-shaped Google Glass.
