Google Clarifies Android Auto USB Lockout in v17.2 as Advanced Protection Blocks Locked Phones
1 articles · Updated · Android Authority · Jul 3
Summary
Android Auto v17.2.662614 contains new text and notifications that explain why some wired connections fail when a phone is locked, rather than silently leaving users to troubleshoot cables, ports or software.
Advanced Protection Mode is the cause: on Pixel 6 and later, its USB Protection blocks data access over USB-C until the device is unlocked, overriding Android Auto’s “start while locked” setting.
Google’s planned fix is explanatory, not a security rollback—the setting will warn that USB auto-connect is disabled by Advanced Protection Mode and that wireless connection still works.
A new lock-screen alert will also tell users “Advanced Protection is on” and that unlocking the phone is required to start Android Auto, addressing a long-running source of confusion for Pixel users.
The changes were found in an APK teardown, so rollout timing is unclear and the feature may still change before public release.
