Why samsung hiding apps ?

[sivisvek]

WHEN I WAS LOOKONG INTO ROOT FOLDER I HAVE FOUND A FOLDER NAMED PRIV-APPS. WHEN I OPED THAT FOLDER I HAVE FOUND MORE INBUILT APPS . SUCH AS APP LOCK , KNOX GUARD ,ETC . BUT IT NOT BE ABLED TO BE USED . WHEN I CLICK THE APK ICON IT SHOWING " DO YOU WANT REPLACE THE EXISTING IN BUILT APP " BUT WHEN I SEARCH THE APP IN SETTING IT IS NOT SHOWING. SO , SAMSUNG IS HIDING APPS FROM US .

Then it is necessary for your device.
S secure won't work without it.

But it is working

Yes. It will work. App lock is installed on your device(hidden).

No idea then. App lock was hidden in A50, which I was able to access via activity launcher https://play.google.com/store/apps/details?id=de.szalkowski.activitylauncher

I have no idea why it is there if S secure is not supported

The lock apps and mask option is available in advanced features in settings.
