GoKawiilSamsung lacks single app-lock toggle, relies on Secure Folder and app pinning instead
Unlike iPhones, which let users lock individual apps behind Face ID with a simple long-press, Samsung's Galaxy phones have no built-in one-tap app-lock feature. Instead, Samsung splits the function across two separate tools: Secure Folder, which hides and protects a set of apps behind authentication, and app pinning, which restricts the phone to a single app until unlocked.
