In December, OnePlus released the first stable build of OxygenOS 12 based on Android 12 for the OnePlus 9 and OnePlus 9 Pro. However, OnePlus halted the distribution a few days later due to a variety of concerns. OnePlus resumed the distribution a few weeks later, with various bug fixes and enhancements. OnePlus released a new OxygenOS 12 update with a few extra improvements and bug fixes at the end of last month. Now, the business is pushing out yet another upgrade to the stable channel, this time with the January 2022 Android security updates.
Oneplus 8, 8pro & 8T Also got their first open beta based on ColorOS 12 with Improved Android 12. Soon after the recruitment, we got the first ColorOS 12 open beta over the air, ColorOS 12 open beta 1 was an incremental update over Close beta 6 & the update size was only 9Mb.
