The short version
Both have a 7.6-inch inner screen. The Fold8 is the proven, lighter-documented choice (201 g) on Android; the iPhone Duo is for people staying on iOS, with up to 2TB and screens that share one aspect ratio. Ecosystem decides this, not specs.

Where each one wins
- iPhone Duo: matching aspect ratios on both screens, deeper iOS app support, up to 2TB.
- Fold8: Samsung's seventh-generation hinge design, S Pen-era multitasking features, a published weight, and usually more discounting over time.
- If you want a telephoto zoom on a Samsung foldable, neither is the pick: that's the Fold8 Ultra.
Switching cost
Moving from iPhone to Android (or back) means re-buying apps and losing iMessage or Samsung-specific features. That cost is bigger than any spec gap here.

How we researched this
This is a research-based review, not a hands-on test. We did not have these phones in hand. We compared the official specification pages from Apple, Google and Samsung with launch coverage and published reviews from established outlets, and we list every source below. Where sources disagree we say so. Battery and camera claims are the makers' own figures unless we name an independent reviewer. Prices are US launch prices from the official pages and can differ at carriers and retailers.
