OnePlus 3 and 3T are now receiving the latest Oxygen OS 4.1.6 OTA update based on the May 2017 security patch level. Earlier this month, the manufacturer released Oxygen OS 4.1.5 bringing a lot of bug fixes, and many new updates. However, according to the software development team, the OOS 4.1.5 has been withdrawn and a new version has arrived with almost similar update logs. The OOS 4.1.6 comes with almost the same changes and bug fixes as that of the previous one. So upgrade your OnePlus device using the downloads consisting of OTA and full firmware zip from below and flash via stock recovery.

Oxygen OS 4.1.6 for OnePlus 3 and 3T is not based on the latest Android 7.1.2 Nougat, but instead the OOS 4.1.5. Moreover, the two devices have already been promised Android O OTA upgrade later this year or at the most Q1 of 2018. So it doesn’t make sense compiling a complete Android OS at this point when the current OS still needs a lot of improvement. As stated in Oxygen OS 4.1.5, this new OTA update brings a new OnePlus community app v 1.9, newer security patches, battery optimization, VOLTE fix, WiFi fix, Camera bug fix, and much more. See the update log from below.
