I need an android phone that logs me into one fake version of the operating system when I unlock it with one pattern, and another OS when I use my real pattern.

Like a virtual machine kind of deal where the attacker cannot know that there are other logins, or how many. Preferably with some kind of automated system that simulates normal usage so it looks real but boring.

The novel Little Brother by Cory Doctorow comes to mind.

One PIN would log you into your real account, another PIN into a decoy account, and no indication of the other one existing.

That does not exist in the real world.

This is called plausibly deniable encryption, though you cannot hide the presence of the system itself.

GrapheneOS has a Duress PIN feature, which wipes your phone if entered.

It is real on pc, veracrypt hidden partition.

I think it only is truly deniable with a HDD

My LG G2 from 2014 had that, I’m sure there are current ROMs that support this

I know Androids can have user profiles which is what you’re talking about. I wish iOS would do the same thing.

OnePlus phones have the system cloner. You can use a different finger print and/or pin to enter a different system with it's own apps and users.

You can do this on pc with veracrypt hidden partition.

On desktop/laptop I think it only is truly deniable with a HDD. Not sure about phone storage forensics but a Linux phone possibly could work for this. Might try for fun at some point
