Key Settings to Enhance Phone Security
Startlap’s report highlights that most smartphones include tools to filter spam calls and messages. On Android devices, users can enable “Call Screening” and “Spam Protection” through the Google Dialer app. These features use machine learning to flag suspicious numbers and automatically send unknown callers to voicemail. iOS users can activate “Silence Unknown Callers” in the Phone settings, which blocks calls from numbers not in the user’s contacts.

Both platforms also allow users to report spam numbers directly. Android’s “Block and Report” function adds the number to a shared database, while iOS users can report spam through the “Report Junk” option in the Messages app. These actions contribute to broader efforts by telecom providers and app developers to combat fraud.

Third-Party Apps for Additional Protection
Beyond device-specific tools, the report recommends installing trusted third-party apps. Apps like Truecaller and Mr. Number offer advanced caller ID features and community-driven spam databases. Truecaller, for instance, displays user-generated ratings for numbers, helping users identify potential scams.

However, Startlap cautions against downloading unverified apps, as some may collect sensitive data. The publication advises checking app permissions and reading reviews before installation. For users concerned about privacy, enabling “Do Not Disturb” mode during specific hours can also reduce exposure to unwanted communication.

Why These Measures Matter
The rise in phone-based scams has prompted increased scrutiny from regulators. In 2023, the Federal Trade Commission (FTC) reported a 20% increase in fraud complaints related to unsolicited calls. Experts warn that scammers often use social engineering tactics to trick users into revealing personal information.

By proactively adjusting phone settings, users can significantly reduce their risk. “These tools are not foolproof, but they create a critical layer of defense,” said a cybersecurity analyst at the University of California, Berkeley, in a 2024 interview. “Combining device features with user vigilance is the most effective strategy.”

Industry Responses and Future Developments
Telecom companies are also enhancing their anti-scams efforts. In 2025, T-Mobile launched an AI-powered call filtering service, while Verizon introduced a “Scam Buster” feature for iOS and Android. These initiatives reflect growing industry collaboration to address the issue.
