Overview
- In the One UI 9 beta 2 build, dismissing the power menu immediately locks the phone and turns off biometric unlocks so only a PIN, pattern, or password will work.
- The visible Lockdown button has been removed from the power-menu options and replaced with a Medical info button in the beta user interface.
- Community reports and coverage by 9to5Google and Lifehacker confirm the behavior in the beta but Samsung has not said whether the automatic Lockdown will ship in the stable One UI 9 release.
- The change mirrors how iPhones require a passcode after invoking the power menu and aims to guard against forced face or fingerprint unlocking, but it also raises the chance users will be unexpectedly locked out.
- Lockdown has historically been a last-resort security tool and can also be activated through Google’s Find My Device network, so users have alternate ways to disable biometrics if the beta behavior is not adopted broadly.
