How to install Samsung Secure Folder instead of KNOX on Android 7.1.1

[mountain55]

Hi,

I have an old Samsung Galaxy J5 Duos (2016) phone that I bought as a backup device while traveling in Asia a few years ago.

Recently did a software update, the most recent version of Android it will upgrade to is 7.1.1. The phone still has Samsung My Knox installed. Haven't been able to figure out how to upgrade from My Knox to the Samsung Secure Folder -- is this possible with Android 7.1.1?

Thanks in advance for any help with this!

Are there any Samsung experts who could offer some insight on this? Thanks!
