Hey Sally, thank you for reaching out to us. We always appreciate receiving feedback from our valued customers. It seems like you contacted us regarding the S23 Ultra. We see that you reached out about concerns you have about being able to block numbers on this device. Dealing with spam calls or persistent unwanted contacts can be quite bothersome and disruptive. However, if you're using a Galaxy phone with Android 9.0 (Pie) or a later version, there are various effective methods available to block these unwanted numbers. By using these features, you can ensure that their calls and text messages won't disturb you. You can directly block specific contacts from your phone's settings. This will prevent them from reaching out to you via calls or messages. Additionally, Samsung's Smart Call feature is designed to identify and block spam calls, providing you with a more seamless calling experience. Moreover, you can even prevent unwanted callers from leaving voicemails, giving you complete control over who can contact you. We hope that these methods will help you manage and reduce the impact of spam calls and unwanted contacts on your Galaxy devices. If you have any further questions or need additional assistance, please don't hesitate to reach out. Thank you for being a valued customer! -Kelvin
