How to Fix Notification Issues on ColorOS (Chinese Variant)
If you’re using a ColorOS Chinese variant smartphone (Oppo, Realme…), you may notice that notifications don’t arrive on time or sometimes don’t show up at all. This happens because of strict system restrictions, especially an app called Athena, which silently kills background apps to save battery.
In this guide, I’ll show you step by step how to fix notification problems on ColorOS so you never miss important messages or emails again.
1. Adjust App Settings
-
Go to Settings > Apps > Auto Launch
→ Enable Auto Launch for apps that require notifications. -
Go to Settings > Apps > Associated Launch
→ Enable Associated Launch for those apps. -
Go to Settings > Apps > App Management > Manage Notifications
→ Allow notifications for essential apps (Messenger, Gmail, WhatsApp, etc.). -
In Multitasking screen
→ Lock apps so they won’t be closed when clearing background tasks.
2. Adjust Battery Settings
-
Go to Settings > Battery > Power Saving Settings
→ Disable Sleep Standby Optimization. -
Go to Settings > Battery > App Battery Management
→ Set apps to Allow Background Activity.
3. Enable Developer Options
-
Open Settings > About Device > Version.
-
Tap Version Number 7 times until Developer Options is activated.
-
Go back to Settings > System & Update > Developer Options.
-
Enable USB Debugging.
4. Uninstall Athena (System App)
The Athena app is the main reason behind delayed notifications. To fix it completely:
-
Connect your phone to a PC.
-
Open the provided tool on your computer.
-
Select Read Info → Uninstall Athena (it only disables for user 0; the system file remains intact).
Final Result
After applying all these steps:
-
Notifications arrive instantly, without delay.
-
Background apps run more smoothly.
-
Athena no longer kills important apps in the background.
