Arpondas725 , via OnePlus 9 Pro , Jan 16, 2022 : It's been about a month since I bought my OnePlus 9 pro, and I've had glitches from OxygenOS 12 on the notification panel, today my screen blacked out(had to restart it using the volume up and power button) and now the dark mode isn't working with Auto-switch.
