Since last week, OnePlus One was under media scanner for being in the final testing stage of Android 6.0 Marshmallow update. Today, the company has finally started rolling out the update to OnePlus One users. The latest build of the OS is named Cyanogen OS 13 (CM13S).

On its official forum, the company announced that Marshmallow-based Cyanogen OS 13 build ‘ZNH0EAS26M’ is now being rolled out in a phase-wise manner. The post also mentioned that it will take some time to reach every device so users must stay patient.
