Google may block Pixel downgrades to older Android builds

Google appears to be preparing to expand anti-rollback protection on Pixel phones, based on Android 16 QPR1 Beta 1 hints.

The change would prevent flashing older Android builds by extending rollback protections beyond bootloader and firmware.

Google says the move would stop devices reverting to older, potentially vulnerable software, improving security.

The update could reduce flexibility for developers and enthusiasts who flash or revert builds, and Pixel 10 may get it first.
