BUILT IN APPLICATION LOCK

so here's the thing, some 3rd-party apps offer pin code or fingerprint unlock whenever you open them, such as WhatsApp or Telegram offer fingerprint or pin code unlock, especially Telegram you can set entirely different pin code

Secure Folder is a lot secure than app lock, first if there's someone try to steal your data externally, they can't access secure folder because Secure folder is entirely different storage and CPU, especially if you are using Galaxy Phone with "Knox Vault".

Secondly if you want borrow your phone to someone else, you can use pin app feature from settings, just type "pin app" on settings search bar, turn on it, then whenever you wanna borrow your phone to someone else, you need to go to recent apps > tap icon app you wanna show to other person > and tap pin this app, this will keep your phone screen stay inside pin app, and there's no way they know your lockscreen code whenever they try to leave your pin app

Third, if your phone got stolen, most thieves will just wipe your entire phone internal storage data thru recovery mode and what will they do next are selling your phone

Last from me, if you are using a MicroSD card, please encrypt yours, it's available thru settings, so if your phone got stolen, they can't extract your data from your MicroSD card
