OnePlus has announced to release Android 6.0 (Marshmallow) update for all of its devices.
OnePlus 2 and OnePlus One will be getting the latest Android 6.0 Marshmallow update in Q1 2016. On the OnePlus One the Cyanogen OS will be updated to Marshmallow which will be followed by OxygenOS updates later.
And the Marshmallow update for OnePlus 2 will bring the new standardized API for the fingerprint scanner which leads to scrapping-up of the OxygenOS fingerprint implementation.
At this point of time, the latest smartphone, OnePlus X seems to be on hold. Because OnePlus has not provided any time frame for rolling out the Android M update for the OnePlus X.
OnePlus also said that for the time being, they will be pushing more OxygenOS updates as soon as possible.
So Stay Tuned For More.
