Google Adds 7 Cellular Attack Alerts in Android 17 QPR2 Beta 3

Summary
Android 17 QPR2 Beta 3 adds a persistent SIM security timeline that logs modem-detected threats, including attempts by cell networks to access a phone’s IMEI or IMSI identifiers.
The update also introduces a SIM security information screen showing active encryption ciphers across calls, SMS, emergency alerts and data connections for the current SIM.
Seven new warning types were spotted in the beta code: downgrade, imprisonment, DoS, jamming, location tracking, unauthenticated SMS and unauthenticated emergency messages.
Android 16 had already added real-time alerts for unencrypted networks and possible stingray base stations, but those notices were easy to miss once dismissed.
The new features expand Android’s Mobile Network Security from pop-up warnings into a fuller audit trail, though some alert types remain unreleased work-in-progress code.
