Which Android app should I use for protecting my phone on public Wi-Fi?

Norton360 Antivirus & Security is a comprehensive security suite designed for Android that addresses public Wi-Fi risks directly. The app's core strength lies in its proactive Wi-Fi security scanner, which automatically evaluates the safety of networks before connecting and monitors them for threats during use. For users frequently accessing coffee shop or airport Wi-Fi, this provides an essential layer of analysis. The integrated VPN is a key companion feature, encrypting data traffic to shield browsing activity and login credentials from potential snoopers on unsecured networks. Reviews indicate the Wi-Fi scanner is generally effective, though some users have reported occasional, minor bugs where trusted home networks are re-detected, often resolved by a phone restart. The VPN functionality receives positive marks for its ease of use, though it can sometimes be temperamental about disconnecting automatically. Beyond public Wi-Fi, the app includes standard malware protection, web protection to block phishing sites, and device security scans, making it a well-rounded security choice for general use, especially for those who travel or work remotely.
