What happens when you receive a text message that shows no theme?

According to your description, I suggest you try the following methods:

1. Settings-Application Manager-Slide Screen Options (All)-Find Information-Click Enter to clear the data and try again.

2. Try to replace another SIM card.

3. Check whether the mobile phone is equipped with security guards or third-party SMS software, and test it after unloading.

4. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore the factory settings.

If the above method still fails, please send the equipment to Samsung Service Center, and the engineer will check the machine and deal with it.

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.
