The landscape of mobile security has shifted away from traditional third-party antivirus software, as modern Android devices are equipped with built-in security features. Key components of this security framework include Google Play Protect, which blocked 27 million malicious apps in 2025; application sandboxing that isolates apps; proactive permissions that enhance user privacy; AI-powered threat detection for sophisticated attacks; and strict sideloading policies to limit risks from off-market malware. Despite these defenses, threats such as social engineering, phishing, malicious push notifications, and unsecured public Wi-Fi remain prevalent, often evading traditional antivirus solutions. However, certain scenarios, such as frequent sideloading, using older devices, connecting to public Wi-Fi, or suspected infections, may warrant the use of third-party antivirus apps for additional protection. Overall, the built-in security features of Android provide a strong defense for most users, with user education being crucial for effective smartphone protection.
