OnePlus ends software support for its 6 and 6T smartphones
That's not really a surprise given that OnePlus has limited the software support to three years since its OnePlus 3/3T handsets. Each OnePlus flagship phone is entitled to three major OS updates and three years of security updates and 2021 was the end of the road for the OnePlus 6/6T. The last OxygenOS 11 update based on Android 11 came last year in September and more recently, the duo got the December security patch.
So anyone planning to continue using their OnePlus 6/6T might need to look into third-party ROM solutions or accept the fact that you won't be getting the latest Android goodies.
