Apart from LG, Motorola and HTC recently announced the arrival of Android 6.0 Marshmallow for their smartphones. Google is also in development to release stock Android Marshmallow for the Nexus devices starting next week. The update will be available on the Nexus 6, Nexus 5, Nexus 7 2013, Nexus 9 Nexus Player but the Nexus 4, Nexus 7 (2012) and Nexus 10 are excluded from the list due to their dated hardware.

Google officially released Android 6.0 Marshmallow as the successor to the last year's Android 5.0 Lollipop earlier this year. The new operating system comes with features like Google Now on Tap, Visual Voicemail and RAM Manager and includes improvements such as Chrome Custom Tabs, simplified app permissions and Doze power-saving option.
