How to Switch between ColorOS and OxygenOS in OnePlus 9 Pro

In this guide, we will show you the steps to switch between ColorOS and OxygenOS in OnePlus 9 Pro. There’s no denying the fact that since its co-founder left the company, things aren’t going in the right direction for the Chinese OEM. And they have no one to blame but themselves for making such questionable decisions. Among them, the most worrisome and infuriating one from the user’s point of view is their choice of switching over to ColorOS from the current OxygenOS/HydrogenOS.
