iPhone does not have a display setting akin to the privacy screen feature found on some Android phones.

Apps can restrict snapshots, and more recently with captureProtected, but far from completely. Particularly given cameras exist. And this requires the specific apps explicitly (try to) block.

You can request this feature be added: Feedback - iPhone - Apple

If by “privacy screen” you mean the feature that makes your screen unreadable from side angles, the answer is:

You cannot activate it on an iPhone 12 Pro Max because iPhones do not have a built-in Privacy Display feature. Apple has not included such a setting in iOS 26 or any current iPhone model. Reports and videos showing an “iPhone Privacy Screen” toggle are either referring to physical screen protectors or are fake demonstrations. 

A privacy screen is a physical screen you put on your phone, not a setting that can be turned on or off.

A jailbroken iPhone could theoretically implement a software-based privacy screen effect, but with significant limitations.

I would never recommend jailbreaking your device just to obtain a so-called “privacy screen” feature. Any software-based privacy display effect is, at best, an imitation and cannot provide the same protection as a physical privacy screen. In return, jailbreaking can expose your device to security risks, reduce system stability, and potentially compromise the privacy and safety of your personal data. The trade-off simply isn’t worth it for a feature that cannot truly deliver the privacy benefits people expect from a real privacy screen.

A privacy screen is a screen protector that have this feature

one way to get one is from Amazon

Turn Private Browsing on or off on your iPhone

With Private Browsing, Safari won't remember the pages you visit, your search history or your AutoFill information. Private Browsing also ...

A privacy screen is a physical screen that makes the picture terrible when viewing from an angle.

Exactly the opposite of what one looks for in a screen meant for photo editing, where a panel that does not exhibit massive color shifts or brightness changes when you look at it from an angle is a good thing.

That’s why many people who bought the latest Samsung S26 Ultra complained about the screen looking bad.

They turned on the privacy screen feature and were shocked it was dimmer, had a limited viewing angle and looked washed out.

I never turned it on, my screen looks great.

I guess they think it’s magic.
