Google started rolling out Android 6.0 Marshmallow to Nexus users yesterday. According to Google, Android Marshmallow is the smartest Android version to date as it comes with several new features like Now on Tap which is a proactive Siri like personal assistant for your Android device.
Android Marshmallow uses less battery juice to keep your phone running much longer along with new app permissions to give you more control over your privacy.
To save your device’s battery life, Android Marshmallow comes with two new features. Doze, which puts your device to deep sleep state and can save up to 30% of your device’s battery life. App Standby puts your rarely used apps to reduced activity state to conserve battery life.
Along side with battery saving features, Android Marshmallow comes with new app permission settings. With app permissions you can choose permissions you want to grant to each app.
On this version of Android, fingerprint scanner can be used to unlock your device, authorising payments in Google Play Store, signing into 3rd party apps, and authorising payments in Android Pay.
For Nexus 5, Nexus 6, Nexus 7, Nexus 9, and Nexus Player the Android Marshmallow update can be downloaded over the internet. Nexus 5X and Nexus 6P (the latest Android devices) will ship with pre–installed Android 6.0 Marshmallow.
