Samsung mobile phone has a horizontal bar flashing. What should I do?

According to your description, I suggest you:

1. Try to restart the machine.

2. Back up mobile phone data (phone book, SMS, pictures, etc.). ), restore the mobile phone to the factory settings, and initially eliminate the causes of system software conflicts.

If the problem still exists, it is recommended that you take the three-guarantee certificate to the local Samsung service center for detailed testing. Please visit the address of the local service center:
