Android Marshmallow-13

Google will release Android 6.0 Marshmallow for existing Nexus devices starting next week, including the Nexus 5, the Nexus 6, the Nexus 7 (2013), the Nexus 9 and the Nexus Player.

Android 6.0 doesn't bring a huge visual overhaul like last year's Android 5.0 Lollipop, however it does include some interesting new features. The most exciting is likely Google Now on Tap, which lets you pull up contextual information from inside any app. The new update also brings greater control over how third-party apps can access your smartphone's camera and other private data.

Overall, Marshmallow should make for a smoother and more stable experience with plenty of small tweaks throughout the system. Meanwhile, a new feature called Doze helps save battery life by turning of programs that don't need to be running in the background. The latest version of Android also includes support for USB-C and fingerprint readers, though that won't make much of a difference for your older devices.
