Samsung mobile phone can't get the address book, and can't send free short messages by email.

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

1. It is recommended that you uninstall and reinstall the software.

2. Replace other versions, or try to update the software.

3. If other third-party software can be used normally, only this software can't have compatibility problems with the mobile phone system.

4. Update the mobile phone system version and then try to install it.

5. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore factory settings (enter phone settings-reset-restore factory settings).

If the problem still exists, it is recommended that you send your mobile phone to the nearest Samsung service center for testing and further processing. 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.
