Sometimes we wish all manufacturers roll out Android updates as quickly as they can. One company who is trying to get it right is OnePlus. After merging its two separate software teams (the China-only HydrogenOS and OxygenOS), OnePlus has announced that OnePlus 3 owners will be getting the community build of Android 7.0 Nougat in the next few weeks, while the final build will be out before the end of the year. OnePlus 2 users will have to wait a bit, the phone is promised to be getting Nougat also but there is no specific timeframe for it.
