Hello, thank you for your feedback. I understand your concerns on this situation and I will be happy to assist you with blocking spam calls. The Smart Call feature gives you the option to block unknown numbers from any numbers that are not in your Contacts list. Once Smart Call is activated, you won’t be bothered by spam calls or other unwanted calls again. The Smart Call feature may not be available on all carriers, models, or software versions. Tap Caller ID and spam protection, and then tap the switch to turn it on. When your phone rings, the Block number and Report number options will appear at the bottom of the screen. Tap Block number to add the number to your Block list. Here is some additional information on blocking numbers https://www.samsung.com/us/support/answer/ANS00062352/.
For additional assistance with blocked calls, please reach out to your service provider directly.
