OxygenOS 16.0.3 Update: What’s New for Nord CE4 and CE5
The update upgrades both smartphones to OxygenOS version 16.0.3 with the February 2026 security patch, ensuring improved protection against recently discovered vulnerabilities. OnePlus has also resolved a long-standing issue where certain system themes incorrectly displayed “ColorOS” branding. This has now been corrected, reinforcing OxygenOS branding across the interface.
Improved App Drawer and System Features
One of the noticeable enhancements is improved app categorization within the app drawer. New Office and Finance categories have been added, making it easier for users to locate productivity and banking applications. This change benefits users who rely on their smartphones for work-related tasks and financial management.
Private Safe and Smart Sidebar Enhancements
OxygenOS 16.0.3 introduces better functionality for Private Safe. Users can now browse files using the smart sidebar, search content directly from the app drawer, and share files without unlocking them first. These refinements make secure file management more intuitive and accessible.
Call Handling and Network Tweaks
For models using the OnePlus dialer, the update adds an option to disable the “Reply with SMS” feature during incoming calls. Network stability and overall system responsiveness have also been improved, contributing to a smoother daily experience.
