This is a bit of a nothingburger. If someone has access to your device it's game over anyway.
I am more annoyed that banking apps don't have an option to show different views based on pin number. For instance if you are in controlling relationship, partner might ask you to show your bank account to see what you spent money on. That suitcase and storage unit you rented to plan your escape? It's in plain sight and so the beating that follows.
And that is just one angle.
Phones themselves should allow for shadow user accounts, where you log in to completely isolated, encrypted and different environment based on pin number, so you always have plausible deniability.
I don't know if this is common, but at the hospital I work, if I type 1+code as my access code to any door, the door will open, but security will receive an alert as suspected hostage situation.
I've always wondered if an adversary asks me which code is mine, what I should tell them, provided they know about the above rule... Perhaps code-1?
