A message from Samsung fold2 lights up the screen.

Samsung mobile phone automatically lights up when it sends a text message, so there is no relevant setting to control on the mobile phone. If the screen of your mobile phone doesn't light up after receiving a text message, I suggest you:

1. Setup-Application Manager-All-Information-Try to clear data 2. Restart your mobile phone 3. Update your mobile phone system software 4. Back up important data (contacts, photos, memos, etc.) and restore the factory settings. If the problem still exists, I suggest you send your mobile phone to your nearest after-sales service center for testing. When Samsung mobile phone receives messages from third-party software (such as WeChat), the screen will not light up automatically.
