Unfortunately, like Xiaomi MIUI, the Samsung OneUI doesn't have any built in App Lock. Maybe someone doesn't want to put everything in Secure Folder and keep checking it to use specific apps, as Secure Folder doesn't even let your share things saved there with outside apps. Samsung must enable/make a Device level App Lock like Xiaomi. It's actually making oneUI experience pathetic and so much less Secure at the same time for a MI fan.
