Android 6.0 Marshmallow New Features

Android Marshmallow was initially announced at Google I/O on May 28, when it was released as the Android M developer preview. Several updates to the preview came out before Marshmallow was officially named on August 17. Google finally unveiled Android 6.0 Marshmallow, alongside the 2015 Nexus devices, on September 29, 2015.

As usual, Google's Nexus family was first to get the goods, and the brand new Nexus 5X and Nexus 6P were the launch devices for Android 6.0. Factory images for most of the existing Nexus range – the Nexus 5, Nexus 6, Nexus 9 and Nexus Player – appeared on October 5. 

iOS 9.2 New Features

Apple released the first beta of iOS 9.2 on Tuesday, following the official release of iOS 9.1, which included new Emoji, last week.
There are a few noticeable differences in the iOS 9.2 beta 1 release, according to MacRumors. The site dug through some of the code and found that there’s new “Action Extensions” support in Safari that allows third-party applications to tap into Apple’s mobile Web browser.
