Using Cloudflare's 1.1.1.1 DNS on an Android phone provides several security benefits. Firstly, it encrypts DNS queries using DNS over TLS (DoT) or DNS over HTTPS (DoH) through the Private DNS feature, preventing eavesdropping and tampering of your hostname lookups by your ISP or other entities on the network. Secondly, Cloudflare has a strict privacy policy, promising not to log your IP address or sell your data. Thirdly, Cloudflare offers family-friendly versions (1.1.1.2 and 1.1.1.3) which block access to malware, phishing sites, and adult content, adding an extra layer of protection during hostname resolution for all apps on your Android device.
