3. Blocking spam calls through "Phone" and Samsung Members

Spam calls are often more dangerous than SMS: Fraudsters use social engineering to lure out card data or personal information. Samsung offers two tools to combat them: built-in blocking in the application Telephone and a service Samsung Members with a database of fraudulent numbers.

Method 1: Blacklist in the Phone application

    6. Additional measures: how to protect yourself from new types of spam

    Fraudsters are constantly coming up with new schemes to bypass antispam. Of particular danger are:

    • 🤖 Voice spam (robots imitating the voice of bank employees).
    • 📸 SMS with QR codes (after scanning, money is written off).
    • 🔄 Substitution of numbers (calls allegedly from banks or government agencies).
    • 💬 Spam in instant messengers (WhatsApp, Telegram).

    How to protect yourself:

    1. For voice spam:
      • Enable in Samsung Members option Alert about suspicious voices.
      • Use the voice assistant Bixby to filter calls: say "Hey Bixby, turn on Do Not Disturb for unknown numbers."
    2. For QR codes in SMS:
      • Never scan QRs from unverified sources. The bank will never send a code to confirm payment via SMS.
      • Install an application QR Scanner with a link checking function (for example, Kaspersky QR Scanner).
  • To replace numbers:
    • Call back to the bank number from the official website (not on an incoming call!).
    • Enable the Google Messages option Authentication of calls (experimental function).

    • 💬 In Telegram: Settings → Privacy → Calls → Who can call → My contacts.
    • 🔍 Use a bot @SpamBot in Telegram to check suspicious accounts.
