What's the best Android app for automatically blocking scam and fraud calls?

Truecaller is a widely-used call management application designed to combat unwanted and fraudulent calls. For users plagued by scam calls, it offers a robust solution by leveraging a crowdsourced database of phone numbers to provide real-time caller identification. When a call comes in, the app displays whether the number is associated with spam, fraud, or telemarketing, allowing users to decide whether to answer or block it automatically. Specific features include automatic spam blocking based on community reports, a continuously updated spam list, and integration with the phone's dialer for seamless operation. In a real-world scenario, someone receiving frequent phishing attempts or fake tech support calls would see these flagged immediately, reducing the risk of falling victim to scams.

Reviews indicate that users appreciate the app's accuracy in detecting scam numbers, with many noting a significant drop in fraudulent calls after installation. The free version covers core functionalities like basic caller ID and spam blocking, making it accessible without a subscription. However, there are limitations: occasional false positives can occur, where legitimate calls are mislabeled, and the app requires an internet connection for real-time updates. Some users express concerns about data privacy, as Truecaller collects call logs to improve its database. Despite these drawbacks, it remains a solid choice for Android users seeking reliable protection against scam and fraud calls, with optional premium features offering enhanced control and ad-free experience.
