According to Carl Pei, OnePlus Co-founder, the first devices to get Android Marshmallow will include the OnePlus One and OnePlus 2 via Cyanogen OS, while OxygenOS will be updated later on. Last but not least, OnePlus X is also scheduled to receive Android 6.0 in the future. Unfortunately, there is no word yet on when the smaller device will get it.
OnePlus will begin rolling out Android 6.0 Marshmallow starting the first quarter of 2016 to its 2014 and 2015 flagships, while the OnePlus X will get it later on.
