I think like/in the secure folder there should be an inbuilt Applock feature in samsung. As fas as i knw most of the Samsung users are searching on youtube and Google if there is an "inbuilt app lock on samsung" or "App locks for Samsung". So atlest in the One UI 6 update please provide an inbuilt app lock for Samsung smartphones. It's a feature that we all need and is waiting for. And I'm 100% sure that it will help many users.
