Why are there so many garbled characters appearing in my S4 phone contacts?

Dear Samsung users:

According to your description, please refer to the following:

1. Turn off the phone and restart it

2. It is recommended to enter Settings-Application Manager-All-Samsung Chinese Input Method-Clear Data to try.

3. Verify whether there is a new input method or third-party software installed on the phone. It is recommended that you uninstall it

4. Back up phone data (phone book, text messages, pictures, etc.) , restore the phone to factory settings (Settings-Reset/Privacy/Private-Restore factory settings)

If the above method still cannot solve the problem, it is recommended to send the phone to the nearest Samsung service center

It is recommended that you make an "appointment in-store" maintenance application on Samsung's official website to enjoy priority maintenance services: /pre-booking

After a successful appointment, please bring your machine, invoice and warranty card to visit you on time Service center by appointment.
