Yes, Samsung has temporarily removed or hidden the Lockdown Mode toggle in the current One UI 9 Beta. [1]
Many users running the One UI 9 Beta on the Galaxy S26 Ultra have reported that the "Show Lockdown option" has vanished from its usual spot under Settings > Lock screen and AOD > Secure lock settings. [1, 2]
What is Happening in the Beta
Known Behavior/Bug: According to community reports on the Samsung Community and Reddit, the toggle itself is missing, but the core functionality seems to be forced or bugged.Power Menu Glitch: Several beta testers have noted that simply pulling up the power menu now acts like an unintended "instant lockdown". If you open the power menu and then change your mind, the phone forces you to use your PIN/Password to unlock it, automatically bypassing biometrics. It also forces a password check before letting you power off or restart. [1, 2, 3, 4, 5]
How to Proceed
Report the Bug: Since this is a beta, Samsung heavily relies on user feedback. Open the Samsung Members app, go to Support > Send feedback > Error reports, and mention the missing Lockdown toggle.Wait for a Future Beta Patch: Samsung frequently adds, removes, or re-allocates security features during testing. The feature will likely be reinstated or moved to a different privacy/security sub-menu in a later beta release.Rollback if Vital: If you rely heavily on manual Lockdown Mode for your daily security routine, your only immediate option is to roll back to One UI 8.5 using Smart Switch until the final, stable version of One UI 9 launches.
