The Nexus 6 was announced October 15, 2014 by Motorola Mobility in partnership with Google. It was the first 6-inch smartphone in the mainstream market, and came with many high-end specs. It was the successor to the Nexus 5, Google's previous flagship phone from their Google Nexus series of devices. Its design was similar to the Moto X (2nd generation) but with a larger display and dual, front-facing speakers rather than the single front-facing speaker on the Moto X. It was the first phone running vanilla Android Lollipop, receiving software updates directly from Google. It was later updated to Android Marshmallow in 2015 and Android Nougat in 2016, though later versions of Android 7.X took some time to arrive, and it never received Android 7.1.2 update, ending its support with Android 7.1.1 in the end of 2017.
