Google recently revealed its next version of Android, Android M. The new M ROM version is mostly same as Android 5.0 Lollipop which also launched this year. It’s worth noting that this is very fast that Google launched two versions of Android in a year. Google says that this version of Android is much more secure than Android 5.0 Lollipop. There are also some user interface changes which makes it more modification-friendly. Now if you have one of the Nexus devices mentioned in the title, just take it out because we going to update it to the latest Android M developer preview version of Android.

Up until now, users know Android Lollipop as the software version to own since it comes with Android Beam, Android Runtime and not the old Dalvik system, a new Easter Egg, Material Design flowing through the UI, Material Design all through the app draw, plus a range of other features. You also get tap and go for the NFC payments, new camera updates, new security updates and still more.
