How to Block Spam Calls on a Samsung Galaxy Phone

Samsung Galaxy phones ship with a built-in spam-call filter called Smart Call. It checks incoming calls against a caller-reputation service - Samsung's Smart Call page says the features are provided by Hiya - and labels calls on the incoming-call screen so you can decide. This guide follows Samsung's own support pages: how to turn the filter on, how the two blocking levels differ, how to block or report a number mid-call, and the limits Samsung itself documents.

When an unknown number calls, Smart Call marks the call on screen. Samsung's Smart Call overview lists the labels: calls can be shown as not suspected to be spam, suspected to be spam, or potential fraud. From the same screen you can block the caller or report the number - Samsung's flow lets you pick the type of spam, add a comment, and submit the report.

Per Samsung's support article on blocking spam calls with Smart Call, the setting lives inside the Phone app itself: open Phone, tap More options (the three vertical dots), tap Settings, then tap Caller ID and spam protection and turn on the switch at the top. Samsung says you will be asked to review terms and a privacy policy and tap Agree before the service activates.

Smart Call can do more than label calls - it can block them for you. Samsung's article describes a Block spam and scam calls switch with two choices: one that blocks calls flagged as spam or scam at any risk level, and a stricter option labeled Only block high-risk scam calls that stops the most serious flagged calls while letting less severe spam ring through. The right choice depends on your tolerance for missed calls: the stricter setting is less likely to interrupt a caller who was flagged lightly, the broader setting is quieter but trusts the reputation service more.

The filter is not the only control. During or after an incoming call, Samsung's article describes tapping Block/Report number at the bottom of the screen. Block number adds the caller to your blocked list; Report number lets you select a category for suspected fraud, optionally add a comment, and submit it.

Samsung is direct about where Smart Call may not exist at all: its article notes the feature availability varies by carrier and device model, and its overview adds that available functions and features vary by country and device. Samsung also notes that using mobile data for the service may result in additional charges. And because labels come from a caller-reputation service, treat them as a signal rather than proof - for anything involving money or sensitive information, verify through a channel you know is genuine.

Smart Call judges a call by the number's reputation. FilterMyCalls adds the other half: it is an AI call screener and spam blocker focused on calls, answering unknown callers before your phone rings, asking each caller for their name and reason for calling, and showing you the response so you can answer, decline, or take a message. Because setup uses conditional call forwarding, it works on the number and carrier you already have - on Galaxy phones and other Android devices, as well as iPhone.

FilterMyCalls works in the U.S. and Canada for US$8/month or US$80/year, and CA$10/month or CA$100/year in Canada. 24/7 Customer Service is included.
