What if the message doesn't light up when adding a mobile phone screen?

If you are using an OPPO/ One Plus mobile phone, you can refer to the following treatment methods if the information is not bright when the screen is off:

1, ColorOS 12. 1 and above: Go to Settings >; Sound and vibration >: Do Not Disturb > Allow notification mode > Lock screen notification > Select "Lock screen notification highlight" or "Settings >; Notifications and status bar > screen lock notification > turn on "open screen notification when screen is locked".

2. Coloros11-12 version of mobile phone: enter "Settings >; Notification and status bar > notification management > more ",and turn on the switch of" Notification screen lights up when the screen is locked ".

3.ColorOS version 3-7.2 mobile phone: enter "Settings >"; Notification and status bar, and turn on the switch of "light up the screen when locking the screen" or "light up the screen when locking the screen".

4. If this happens after using the tripartite theme recently, I suggest you try to replace the original theme of the system.
