OnePlus Rolls Out Marshmallow Based OxygenOS 3 for the OnePlus 2
After several months of beta testing, the OnePlus team has finally released their Android Marshmallow based OxygenOS 3.0.2 build. Based on the forum post made by the OnePlus team, the OTA update is just now rolling out and it will be done incrementally so it could be up to 48 hours before your OP2 sees the update hit it. Once it does, you will have a Marshmallow 6.0.2 base along with all the goodies that come with it and the ones that OnePlus has baked into OxygenOS.
