CVE-2019-20569

Factory Reset Protection bypass via status bar

Published Mar 24, 2020 · Updated Aug 5, 2024

Authentication bypass in Samsung mobile devices running Android 9.0 allows physically proximate attackers to defeat Factory Reset Protection. Published records identify the status bar as the bypass path but do not disclose which status-bar action or handler fails to enforce FRP. Physical access to a reset device is required, and exploitation permits protected device setup to proceed without satisfying the prior ownership check.
