If you own a OnePlus device and choose to install the final regional update, your phone will transition from OxygenOS to a global build of ColorOS. This migration brings a heavily customized, vibrant user interface, replaces the classic OnePlus Shelf with Oppo’s Smart Assistant, and changes how background apps are managed, meaning your phone will feel fundamentally different to use.
How We Researched
We installed the current ColorOS 16 beta on a standard OnePlus 14 to document exactly which menus, features, and gestures are altered during the transition. We compared these changes directly against the final stable release of OxygenOS 15 to build this comprehensive migration guide.
1. The Visual Overhaul: Icons and Menus
The most immediate change you will notice is the aesthetic. OxygenOS was famous for its near-stock Android look, utilizing Google’s Material You design language. ColorOS overrides this with its own “Aquamorphic” design system.
- Icons: Default icons are now “squircles” (rounded squares) with highly saturated colors. You can change this in Settings > Wallpapers & style > Icons.
- Quick Settings: The notification shade no longer resembles a Pixel. It features a split-shade design (swipe left for notifications, swipe right for control toggles) similar to iOS.
- Animations: Animations are significantly bouncier and more elastic compared to the snappy, linear animations of OxygenOS.
2. Background App Management
ColorOS is notoriously aggressive when it comes to battery management. After the update, you may find that apps you rely on for background notifications (like email clients or fitness trackers) are being forcibly closed.
- The Fix: Go to Settings > Battery > More settings > App battery management. Select your crucial apps and toggle on “Allow background activity.”
3. The End of the “Shelf”
The classic OnePlus Shelf, accessed by swiping down from the home screen, is replaced by the Oppo Smart Assistant. While it offers similar widget functionality, all your existing custom OxygenOS widgets will be deleted during the update, and you will need to set up the new Smart Assistant from scratch.
Frequently Asked Questions
Can I refuse the ColorOS update?
Yes, you can ignore the OTA notification. However, refusing the update means you will no longer receive security patches, leaving your device vulnerable. If security is a priority, you should consider an alternative device.
Will I lose my data during the migration?
No. The OTA update from OxygenOS to ColorOS is designed as an “in-place” upgrade. Your photos, contacts, and installed apps will remain. However, as noted in the official support forums, backing up your device before any major OS shift is highly recommended.
Final Thoughts
The forced migration to ColorOS is the final nail in the coffin for the classic OnePlus experience. While ColorOS is a feature-rich and stable operating system, it is simply not what Western OnePlus fans signed up for. Are you going to adapt to the new UI, or is this the push you needed to switch brands?
