Samsung Galaxy phones with Smart Call can identify callers outside your contacts and let you block or report unwanted calls in the Phone app. The setting is built in, but availability depends on your carrier, device, and country—and Samsung warns that mobile data charges may apply.
Does Samsung Galaxy have a free spam blocker?
Samsung calls its built-in call identification and blocking service Smart Call. It is part of the Galaxy Phone app and can identify callers who are not saved in your contacts, as well as help you block or report calls.
Samsung says Smart Call features are provided by Hiya. A 2021 FCC filing described Samsung’s Hiya-powered service as providing caller ID, spam flags, and automatic blocking of known fraud calls “at no additional charge.” That is a dated description, not a guarantee about every current device or plan. Samsung cautions that using mobile data for Smart Call may result in additional charges.
How do I block spam calls on my Samsung Galaxy?
- Open the Samsung Phone app.
- Tap More options (the three-dot menu), then tap Settings.
- Tap Caller ID and spam protection. Review the terms and privacy policy, then enable the feature.
- If shown, open Block spam and scam calls and select the level of blocking you want.
Samsung documents this path in its US Smart Call setup guide. Exact availability and labels can differ by country, model, carrier, and software version.

Should I block all spam calls or only high-risk scams?
Samsung’s documented settings offer two choices. The broader option may stop more calls labeled as spam or scams, but it may also block more calls you would have wanted. The more selective option lets lower-severity spam through. Samsung does not provide comparative detection-accuracy figures for these settings.
| Setting | How it behaves | Trade-off |
|---|---|---|
| Block all spam and scam calls | Blocks calls identified as spam or scams. | More aggressive; greater chance of a wanted call being blocked. |
| Only block high-risk scam calls | Blocks calls classified as high-risk scams. | Narrower; less severe spam may still reach you. |
You can also block or report an individual call during or after it. In the Phone app, open the call details or call log entry and use the available block or report option.

What if “Caller ID and spam protection” is missing?
Do not assume every Galaxy phone has the same Smart Call controls. Samsung says availability can vary by carrier and model, and its feature information also notes differences by country and device. Check with your carrier and confirm your phone model, country settings, and software version. Samsung recommends updating the phone software or troubleshooting the Phone app if Smart Call is not working.
How is Smart Call different from blocking unknown numbers?
Spam identification uses Smart Call’s caller information to flag unwanted calls. Separately, the Phone app’s Block numbers control can block numbers that are not saved in your contacts. That broader rule may silence legitimate first-time callers, such as a delivery driver or clinic. Blocking voicemail from a particular caller may require contacting your carrier.

What about Samsung AI Scam detection?
AI Scam detection is a separate feature, not another name for Smart Call’s spam-blocking setting. Samsung’s US guide limits it to Galaxy phones running Android 16 with One UI 8.5 or higher. It alerts you to a suspected scam and leaves the decision to answer or block to you; it does not automatically make that choice.
