There's something about a flip phone that just makes you feel powerful—especially that satisfying snap when you end a call. The good old days are back, refined. After two months with the Samsung Galaxy Z Flip 4, here's the honest verdict: this might just be the best compact foldable on the market.
What's in the Box (and What Isn't)
Open it up and you get the phone, a USB-C cable, and a SIM ejector tool. That's it — no charger in the box (though Samsung frequently throws in a 25W brick with pre-order deals). Its main rival, the Motorola Razr 2022, still bundles a 33W power brick.
Design: They Flipped It Around
Coming from the Flip 3, the exterior is now matte (Gorilla Glass Victus+) with glossy aluminum sides — the exact reverse of the old glossy-glass, matte-frame combo. The result: less slipping on tables, more premium in hand.
The Hinge & Flex Mode
The hinge is slightly slimmer but just as sturdy — and Flex Mode lets the phone hold any angle. Optimized apps split controls to the bottom half of the screen; unoptimized apps can be forced into it too. There's still a small gap (so it's IPX8 water-resistant but not dust-rated) — though Samsung's oleophobic interior coating protects the internals, and the design pushes dust back out.
That Useful Outer Screen
The 1.9" AMOLED cover screen isn't just for notifications. Swipe through quick toggles, read and dictate messages, run themed animations (yes, the Star Wars one shoots the Death Star). Keeping it folded also protects that soft inner display from drops.
The Inner Display & Performance
Unfold to a 6.7" AMOLED, true variable 1–120Hz panel with dual-firing speakers and a side-mounted fingerprint reader. Powered by the Snapdragon 8+ Gen 1, it handles daily tasks buttery-smooth. The catch: heavy gaming throttles after ~5 minutes — two bricks in one leaves little room to dissipate heat. Casual gaming is totally fine.
Battery & Cameras
The bumped 3,700mAh battery makes it a proper all-day phone, with 25W fast charging (~55% in 30 min). The dual 12MP + 10MP cameras lean on Samsung's mature computational photography — delivering more consistent shots across lighting conditions than the Razr's higher-megapixel sensor. Pro tip: double-tap the power button and use the cover screen as a viewfinder for the main sensor.
Bottom Line
Coming from the Flip 3, the upgrades are iterative — better battery, matte finish, slightly smaller bezels. The lingering gripe? The crease, still noticeable mid-swipe. But as a compact foldable that slips into any pocket and opens into a full-size phone, it's the best in its class. This is the future we dreamed about decades ago — and it's here.
