Following the initial OxygenOS 4.0.0 release based on Android 7.0 Nougat which went out just as 2016 drew to a close, as well as the 4.0.1 hotfix from last week, OnePlus is now in the process of rolling out a new update to its latest flagship devices.
OxygenOS 4.0.2 is headed to both the OnePlus 3 and the OnePlus 3T. That said, the rollout is incremental as always, meaning that only a small percentage of devices will be updated today, with a broader distribution coming in the next few days.
As you surely could tell from the small version number change, this update isn’t about huge new features (or Android 7.1 for that matter). Instead, for both handsets APN settings have been updated for select carriers, the proximity sensor bug during calls was fixed, as was the Google Play Store download bug, and overall system stability is increased. Wi-Fi connectivity might still fluctuate according to OnePlus.
