Few moths back OnePlus promised to roll out Android 6.0 (Marshmallow) update for the OnePlus One and the OnePlus 2 smartphones in Q1 2016. It released the OxygenOS 3.0 Beta based on Android 6.0.1 for the OnePlus 2 last week. Today OnePlus co-founder Carl Pei revealed that the Android 6.0 (Marshmallow) update with Cyanogen OS 13 is in final testing stage.
Marshmallow for the One is in the final testing stage. Can't give ETA as it depends on other parties, but should be very soon.— Carl Pei (@getpeid) April 6, 2016
Even though we still have to wait for the official Cyanogen OS 13 update, the CyanogenMod 13 nightlies were released back in November and the CM13.0 snapshot was released for the smartphone last month.
Android 6.0 concentrates on App Permissions, Web Experience, App Links and Power & Charging. It also brings new Doze battery saving feature that uses motion detection to cut off background activity when the phone is in standby, but it will still wake up for important events like alarms.
Carl Pei doesn’t confirm when the update will roll out, since it depends on Cyanogen as well.
