Samsung note3 address book interface used to be black words on a white background and suddenly changed to black words on a black background. How to change the white character L on a white background into a black font color? Dear Samsung users, hello:

According to your description, I suggest you;

If the system is upgraded, it is normal and cannot be changed.

1. Try to uninstall the recently installed third-party software (Mobile Guard, Mobile Manager, etc.). )

2. Back up mobile phone data (phone book, SMS information, multimedia materials, etc.). ) and restore factory settings: Settings-Reset-Restore factory settings.

If the problem still exists after the above operation, it is recommended that you bring the purchase invoice, three-guarantee certificate and mobile phone to the local Samsung service center for inspection by engineers.

For specific inquiries about the service center, please visit.
