Samsung One UI 9 removes lockdown button, activates automatically

Samsung One UI 9 eliminates the lockdown option from the power menu and activates it automatically when the power menu is dismissed. The feature now triggers without user input, replacing 'Lockdown' with 'Medical info' in the menu. This change removes user control over emergency access, locking biometric security and leaving only PIN access. The update is based on Android 17 and has been tested in beta versions, with Reddit users confirming the behavior.
