While I am unable to offer specific recommendations, as I have not personally utilized third-party app lockers, I would suggest, from a security and privacy standpoint, that you carefully review the permissions requested by any app after installation...
Yes—Duplicate karta ha. You can safely uninstall that app from phone's main apps (outside secure folder) only if you don't need to use it outside Secure folder.Note: Always backup data before deleting any file or app from phone.
I appreciate your post.That is a very good question. I would advise against using app lockers, as they may not be secure.Instead, you could consider using Samsung's Secure Folder to store your important apps and sensitive data.Please feel free to ask...
