Stable OxygenOS 12 update goes live for the OnePlus 7 and 7T series

If you've got a OnePlus flagship from 2019, prepare to download a fresh new software update. The company waited until July to announce the OxygenOS 12 Open Beta initiative for the 7 and 7T series, more than eight full months after Android 12 went public. Following the usual round of beta testing, a stable build of OxygenOS 12 is now available for the OnePlus 7, 7 Pro, 7T, and 7T Pro, bringing several enhancements to the phones.

The build number of the stable release is H.28 (for the OnePlus 7 series) / F.16 (for the OnePlus 7T series). In addition to everything brought to the table by Android 12, OxygenOS 12 introduces a major visual overhaul to these OnePlus phones. The Android security patch level (SPL) is a bit old, though, as OnePlus ships the August 2022 security patches with these builds.

Here is the complete changelog for the update:
