Google Integrates Gemini into Play Books and Enhances Android Security in June 2026 Update

Google began rolling out its June 2026 system updates on June 15, bringing new artificial intelligence and security enhancements to the Android ecosystem. [2] In the Google Play Books Android app and web reader, users can now access "Book insights," an AI reading companion built with Gemini. [1] This tool operates on select English titles and allows readers to summarize chapters, clarify text, and ask spoiler-free questions by clicking a lightbulb icon. [1]

Alongside the reading assistant, the system update introduces improved scam call detection in the Phone by Google app. [2] The feature attempts to identify spoofed calls by pinging the supposed caller's device to see if it is actively in a call, though both parties must be using the Phone by Google app. [2] The release also enables users to manage WhatsApp backups from device settings and introduces a "Trusted" badge for eligible users in the Google Play Store.

The addition of "Book insights" demonstrates how Google is actively integrating Gemini capabilities into daily consumer media applications, moving beyond generic standalone chatbot interfaces. The scam detection mechanism represents a novel technical approach to spoofing, building upon Google’s previous Advanced Protection tools by utilizing device-to-device pings rather than solely relying on network-level filtering. However, the requirement that both callers use the Phone by Google app may initially limit its effectiveness in broad real-world scenarios. What the sources don't address: whether Google plans to expand the Book insights feature to non-English titles or other reading platforms in the future.
