As mentioned before, the package intends to boost and refine the user experience. Precisely, it improves the system security by integrating the September 2022 Security patch. The patch fixes two dozen of vulnerabilities and protects your device from third-party threats that affect the Android security system. In addition to this, the build resolves an issue where Amazon Alexa would not be enabled occasionally. Refer to the changelog below for more details.
As usual, the OTA update is rolling out in batches. So, the OnePlus 9RT owners can expect the update notification to reach them anytime soon. In the meantime, you can also attempt to trigger the build manually. To do this, head to Settings > Software update.
