It's so inconvenient that Samsung doesn't provide In-built App Locker unlike other brands. While Secure Folder can do the trick, it's not a proper App Lock and duplicates the apps that has to be locked in parallel storage location. Secure Folder has so many disadvantages if you choose to lock an app in it like if you download something in an app locked by Secure Folder, you can't access the downloaded file in normal storage/gallery. Even screenshots took in those apps are not accessible in normal storage/gallery.
and 3rd party app lockers in Play Store/Galaxy Store are so slow and not secure as they can be easily uninstalled by anyone.
So i request to Samsung Devs that please provide in-built App Lock feature in next updates
