What should I do if the screen does not light up when I receive a message when the screen is locked?

The screen automatically lights up when a text message comes in. There are no relevant settings on the phone to control it. If the screen does not light up when you receive a text message on your phone, we recommend that you:

1. Settings--Application Manager--All--Information--Try clearing data

2. Restart the phone

3. Update the phone system software

4. Back up important data (contacts, photos, memos, etc.) and restore factory settings

If the problem persists Yes, it is recommended that you send your phone to your nearest after-sales service center for testing.
