Certainly, the inclusion of an application lock feature is highly desirable, and many smartphone brands already offer this functionality. Considering that the Galaxy Z Fold 7 and Flip series, which run the stable One UI 8 version, Doesn't have this feature, it seems that no other devices with One UI 8 will receive it. It is possible that this feature may be introduced in One UI 8.1 or perhaps even in One UI 9. I have been requesting and waiting for 'App Lock' Feature since One UI 6.
