The caller id of the mobile phone is unknown, so I can't go back for the time being.
According to your description, I suggest you:
1. Open Settings-Application Manager-All-Mobile Phone-Try after understanding the data (excluding system anomalies)
2. Try to replace the SIM card. Maybe the SIM card is not normal.
3. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ), restore factory settings (Settings-Reset-Restore Factory Settings), and eliminate third-party software problems.
If all the above methods fail, it is recommended that you take the three-guarantee certificate you bought and send your mobile phone to the nearest Samsung service center for inspection and maintenance. Please click the following link for the specific location:
