Why didn't the lighting effect in breathing light shine when I applied for notification to GTNeo5?

1. When the mobile phone is on, the notification light effect will not take effect. Please press the power button and try again. 2. Confirm whether the breathing light function is turned on. If breathing light is off, please turn on the switch in Settings > Wallpapers and Personalization > breathing light; 3. Confirm whether the current display interval is breathing light, and the display time can be customized. The opening path is Settings > Wallpaper and Personalization > breathing light > Display Time; 4. breathing light has a certain reaction time. If the response time is exceeded, the light efficiency time will be missed (breathing light display time is 5 minutes); 5. Confirm whether it is preempted by high-priority applications. The priority of breathing light is: camera (countdown) > incoming call > GT mode > notification > low battery; 6. To confirm whether the current application is in the list of breathing light applications, you can manually check it in Settings > Wallpaper and Personalization > breathing light > Applications that support reminder lighting effects; 7. After the power saving mode and super power saving mode are turned on, the breathing light function cannot be used. Please set >; Battery > turn off power saving mode/super power saving mode. 8. When the real GTNeo5 opens, it should be used to inform breathing light that it will not open.
