OPPO ColorOS 16 lets you customize your fingerprint icon with Chinese characters and emoji
There’s a small but telling difference between what Chinese phone makers offer versus their global competitors: the attention they pay to lock screen customization. OPPO and OnePlus just added another option to that list — the ability to customize the fingerprint icon itself.
ColorOS 16 now supports custom lock screen fingerprint styles, letting users choose from Chinese characters, numbers, letters, emoji, and even animations. Instead of the standard fingerprint icon, your unlock button could show a heart emoji, your initials, or the year. The feature rolled out with the 16.0.9.400 update, according to OPPO’s official ColorOS Weibo account. Users who haven’t received the update yet can apply through the early access channel.
The fingerprint customization is just one piece of a much larger June update that started rolling out on June 3. OPPO says it will cover over 100 devices running ColorOS 13 and above, with the full rollout completing by June 30. The update also introduced:
New lock screen widgets. The Lockscreen Island now supports Kugou Music controls. AI Fluid Cloud — ColorOS’s live activity-style notification system — gained support for Super Schedule and calendar course reminders.
Smarter assistant features. Xiaobu (OPPO’s voice assistant) now offers football match viewing cards and a match-watching AI agent. The AI Fluid Cloud system can surface live scores and game schedules on the lock screen.
Cross-device connections. Feiniu Private Cloud now supports seamless connection. OPPO Bubble — a playful selfie screen feature — and a new Dragon Boat Festival watermark were also added.
ColorOS 16 itself launched back in October 2025 at OPPO’s Developer Conference. The company positioned it around two ideas: making smoothness feel effortless, and making AI personal enough to “remember you and understand you.” Under the hood, OPPO rebuilt the system with three new engines — Aurora for animations, Tide for performance scheduling, and a Star Compiler for app optimization — to deliver what it calls “seamless animations across every scenario.”
On the AI side, ColorOS 16 centers on Xiaobu Memory, a system that records multi-modal information through a one-tap flash note feature and serves up personalized briefings and proactive scene-based reminders.
One of the more unexpected features in ColorOS 16 is OPPO Interconnect, which supports notifications, screen projection, and other interactions with iPhones, Macs, and Apple Watches. It’s a pragmatic acknowledgment that even in markets where OPPO sells phones, plenty of users carry Apple devices too.
The fingerprint customization feature is live now for devices on ColorOS 16.0.9.400. If you have a compatible OPPO or OnePlus phone, check Settings — it should be under the fingerprint and lock screen section.
