When the screen of Samsung mobile phone is locked, unconscious touch will automatically light up the screen.

When the phone is locked, the screen will automatically light up. I suggest you:

1. Check whether there are any new short messages on the mobile phone. Settings: Information-Menu Key-Settings-Notification Information Settings-If there is a screen lighting option, please turn it off.

2. It is suggested to check whether the mobile phone has a quick look function. Please operate: Settings-Control (My Device)-(Actions and Gestures)-Gesture Sensing-Quick List Off (or Settings-Auxiliary Functions-Agility and Interaction-Wake-up-in-the-Air Off), and then observe whether the machine has the same situation.

3. Check whether the third party locks the screen or the theme software causes the uninstall attempt.

4. Back up data (contacts, text messages, photos, etc. ) and restore factory settings (Settings-Reset/Privacy-Restore Factory Settings).

If the problem still exists, it is recommended that you take the machine, purchase invoice and warranty card to the local Samsung after-sales service center for testing. Samsung service center address inquiry website:

. Samsung . com/support/service locations . ASP

It is recommended that you apply for "booking to the store" in Samsung official website and enjoy priority maintenance service:/pre-order.

After the appointment is successful, please bring your machine, invoice and warranty card to the service center you reserved on time.
