Why does my s8 light up automatically every time I receive a text message?

If the screen lights up automatically when the phone is locked, it is suggested that:

1. Check whether the mobile phone supports easy screen opening function: Settings-Accessibility-Agile Interaction-Easy screen opening-Off.

2. If not, please unlock the screen and see if there is any new information notification. If so, it may be caused by setting the "Lock screen display notification" to "Don't display notification".

3. If there is no new message prompt, please check whether you use third-party theme software, and suggest changing it to your own theme.
