Finally, OnePlus 3 and 3T users are receiving a new software update. The latest update brings Android September 2018 security patch alongside OxygenOS 5.0.6 or a few other improvements.
OnePlus has confirmed that OxygenOS 5.0.6 is now available for download for OnePlus 3 and 3T users and it brings along the latest Android security patch for the month of September 2018. In the changelog, OnePlus also notes that this update fixes bugs and improves general system stability.
This OTA will have a staggered rollout, the OTA will be received by a limited number of users today and will have a broader rollout in a few days after making sure there are no critical bugs, so using VPN to download this build might not work as the rollout Is not based on regions and is randomly pushed out to a limited number of devices.
