Change Always-On Display Clock Style auf Oppo
The Always-On Display on Oppo phones is not limited to time and battery percentage. Since the feature launched on ColorOS, Oppo added individual toggles for date and notification previews, but many users never open the right settings screen to enable them.
By default, some Oppo units only display the clock and a minimal battery icon. If notifications feel invisible without unlocking the phone, or the date is missing from your lock screen glance, the fix sits inside the display settings rather than in a separate app.
Where to change it
Go to Tap on Settings ➔ Tap on Home screen, Lock screen & Always-On-Display ➔ Tap on Always-On Display ➔ Turn On/Off Date, Notifications or Battery. Each element has its own switch, so you can keep the display minimal or show all three at once.
Turning on notification previews here does not change your general notification settings elsewhere. It only controls whether incoming alerts appear on the always-on screen. If you use a screen lock for privacy, keep this in mind before enabling previews on a shared device.
