OnePlus may be slow to update many of its phones to the new version of Android, but the company is still doing the right thing (usually) to make security fixes. The OnePlus 6 and 6T are currently three years old, but security updates are underway for both phones, and now the November 2021 patches have arrived.
OxygenOS 18.104.22.168 is now available on the OnePlus 6 and 6T. The change log only mentions “improved system stability” and the November 2021 security patch level, with no other changes apparently. This is OxygenOS 22.214.171.124, the first update for both phones since September 2021, which brought patches and various bug fixes.
This may be the latest official update for both the OnePlus 6 and 6T, as they promise only two years of Android updates and three years of security fixes. By 2021, both phones will still be strong enough, and the OnePlus will unlock the bootloader and make it easy to install custom ROMs, so if you’re interested in keeping your OnePlus 6 or 6T, visit the forum for each device (link below). updated.
