OxygenOS for OnePlus 11R

With the integration of the February 2024 Android security patch, OnePlus 11R users will get an enhanced level of system security. This update is crucial for protecting the device against the latest security threats and vulnerabilities.

A notable feature of this update is the upgrade to the high-frequency PWM (Pulse-Width Modulation) dimming technology.
