Google has started the roll out of Android 6.0 Marshmallow Updates for their latest flagship tablets like the 2013 Nexus 7 and Nexus 9 models. Check your device's notification screen and make sure to confirm the download and installation process of Android 6.0 firmware update.
The Android 6.0 Marshmallow update is being released in stages for all Nexus 7 2013 and Nexus 9 tablets worldwide. You will be getting the new update only if your tablet sports the previous Android 5.1.1 firmware on it.
The Nexus 7 2013 LTE, Nexus 9 Wi-Fi and LTE models are the first devices to run the full Android 6.0 firmware, while the Nexus 7 2013 Wi-Fi, Nexus 5 and Nexus 6 devices should get the OTA Update in the next few days.
There are some older Nexus models such as the the 1st-gen edition of Nexus 7 tablets and Nexus 4 smartphones are not going to be upgraded to Android 6.0 Marshmallow. If you own one of those devices and you want to run an Android 6.0 firmware, then your best bet would be to wait for Android 6.0 to reach AOSP Development stage and see new Android 6.0 custom released.
Android 6.0 Marshmallow brings the 'Now on Tap' feature that is capable of pulling relevant information out of your emails and from other apps you're using on your device. If you get an email that contains a place where you have to meet someone, then 'Now on Tap' feature will start and will show info such as Google Maps directions, contact info, and other shortcuts to other helpful apps. Also, with 'now on tap' you can easily create calendar entries for event time, data and event location.
Doze is another great thing added by Android 6.0 Marshmallow, as it offers better battery life and improved deep sleep state to conserve as much power as possible. From now on your device should be able to handle better the remaining charge levels.
Doze in Android 6.0 Marshmallow will know when your Android device is idle and it will instantly put it in deep sleep state in order to save as much power as possible. Another great function of Doze is the App Standby, as this will tell the phone to save battery power by reducing the activity state of apps you barely use and conserve battery power for applications that you are using frequently.
Android 6.0 Marshmallow will also better protect your privacy and offer you the possibility to control and customized your apps permissions. This means that you can allow and deny permissions for various apps while still being able to use the app. This new Android 6.0 is an evolution of Android 5.1.1 and it should be much more stable and smoother than before.
