In our earlier posts, you might have read us talking about the new Android M rolling out on the Google Nexus.  The Nexus are, no doubt, one of the leading smartphones in terms of power and quality. And that’s why you can now update your Nexus 5, 6, 9 and Nexus Player to the Android M developer version. According to the news, the developer version of Android M is showing improvements, keeping in mind that it still hasn’t reached the final stage and it isn’t completely ready. The most astonishing thing is that you can now enable the multi-window option on it.

It should be kept in mind that the android M is only meant for developers, and it’s going to be laggy and going to have a lot of problems. The new developer’s version update is still in the process of development so when you install it on your Google Nexus device, you might experience some bugs. Don’t worry: it will all be fixed when the official version rolls out later in November 2015. If you have peaked around to see what should you be expecting from the Android M, you can easily reinstall or downgrade to Android Lollipop.

The multi-window option isn’t displayed to the normal users. But you can follow this step by step guide to enable the multi-window function. This functionality is, again, still in the process of development and it need a lot of improvement. We hope to see that in the near future.

Enough talking. Let’s get down to business!
