How to install two app instances on the same phone?

I have tried to install the second app instance in secure folder, but it failed.

possible.
What app are you trying?

Samsung Galaxy devices offer a Secure Folder, allowing a second installation of the same app. The folder is basically a phone within a phone: things outside the Secure Folder don't interact with the contents of it, and vice versa. That's the only instance I know of wherein you can have the same app running twice.
