The OnePlus 3 has been on sale since June 2016, up to now, for a total of 41 months (3 years and 5 months). OnePlus 3T began selling in November of the same year.
The final update will be OxygenOS 9.0.6, which will be released for both OnePlus 3 and 3T. Mainly, it will upgrade security patches to October, fix bugs and update GMS apps in the system to the latest version. This update doesn’t stand out. As it is a small monthly security patch update
Last year, OnePlus stated that the OnePlus 3 will receive the latest Android update 24 months after the release (ending at Android 9 Pie) and will receive a security patch for another 36 months, which if counted accordingly. The 41-month long haul is considered to be beyond the expectations of many as well. The main reason is that the OnePlus 3T has to be updated for 36 months and the two models have similar specifications. Much Causing the pre-release model OnePlus 3 to receive an extra-long update
