Samsung Galaxy Z Flip4 F721U Graphite 128GB

The foldable 6.7-inch Dynamic AMOLED 2X display with 120Hz refresh and Snapdragon 8+ Gen 1 chip provides fluid visuals in a device that collapses into a compact 142-gram form. Its dual 12MP cameras offer versatile shooting while the pocketable design and lightweight build enhance daily carry. This phone is best for style-conscious users prioritizing portability and casual photography, but its 9.5/100 ruggedness score means it’s a poor fit for harsh or outdoor-heavy use.

Snapshot

The 30-Second Version

The Z Flip4 is a cheap ticket to flip phone fun, but the battery and camera will make you work for it. Buy it for the form factor, not the specs.

Pros & Cons

Pros

  • Genuinely compact when folded, fits anywhere 73rd
  • 120Hz AMOLED display looks great for the price
  • Snapdragon 8+ Gen 1 still handles daily tasks fine
  • Cheapest way into Samsung's flip lineup at $430

Cons

  • Battery life is one of the worst we've seen
  • Camera setup is basic and underwhelming
  • Build quality feels fragile compared to slab phones
  • No meaningful social proof or customer reviews yet

The proof

Performance

The Snapdragon 8+ Gen 1 is still a capable chip, but it's not winning any races in 2025. Our benchmarks put this thing in the 22nd percentile for performance, which means most modern flagships leave it in the dust. That said, day-to-day scrolling and app switching feel fine thanks to the 120Hz panel. The real surprise is how well the foldable display holds up visually. It's a strong 73rd percentile for display quality, which is better than you'd expect from a phone this cheap. Just don't expect it to stay cool or last long under heavy gaming loads.

vs Competition

The obvious rival is the Motorola Razr Ultra 2025, which offers a more polished flip experience with better build quality and a larger cover display. The Z Flip4 feels dated next to it. Against the iPhone 16 Pro Max or Pixel 10 Pro XL, this isn't even a fair fight. Those phones crush it in camera, battery, and performance. The OnePlus 13 also beats it on nearly every metric while staying in a similar price bracket. The only reason to pick the Z Flip4 over any of these is the flip form factor and the $430 price tag.

Price

Value & Pricing

At $430 unlocked, this is a decent deal if you specifically want a flip phone. You're getting a foldable AMOLED display and a capable processor for less than half the price of a new flagship. But you're also getting a phone with a 9th percentile battery and a camera that's below average. If you don't care about the flip form factor, there are better slab phones at this price. If you do care, this is the cheapest ticket in.

Overview

The Galaxy Z Flip4 is the phone you buy because you want a flip phone, not because you want the best phone. It's a 6.7-inch foldable with a Snapdragon 8+ Gen 1 and a 120Hz AMOLED display, and at $430 unlocked, it's one of the cheapest ways into Samsung's foldable lineup. But the compromises are real. The camera setup is basic, the battery is rough, and the build quality sits near the bottom of our database. If you're after the flip form factor and don't mind charging mid-day, this is a fun little pocketable. If you want a flagship experience, look elsewhere.

Common Questions

Q: How long does the battery actually last?

Not long. It's in the 9th percentile for battery in our database, which means you'll be reaching for a charger by mid-afternoon with moderate use. Plan on topping up if you're out all day.

Q: Is the camera good enough for social media?

It's fine for casual shots in good light, but the 12MP main and ultrawide are pretty basic. Low light and zoom shots will disappoint. If photos matter, get a Pixel or iPhone instead.

Q: Does the crease in the display get annoying?

You'll notice it at first, especially when scrolling. Most people get used to it within a few days. It's more visible than on newer foldables, but it's not a dealbreaker at this price.

Who Should Skip This

If you're looking for a phone with all-day battery life, a great camera, or a rugged build, this isn't it. Go get a Pixel 10 Pro XL or an iPhone 16 Pro Max instead. And if you want a flip phone that doesn't feel like a compromise, the Motorola Razr Ultra 2025 is the better choice, just be ready to pay more for it.

Verdict

Buy the Galaxy Z Flip4 if you want a flip phone and you're on a budget. It's not a great phone by 2025 standards, but it's a fun one, and at $430 it's hard to argue with the price. Just know what you're signing up for: mediocre battery, a basic camera, and a build that feels more delicate than a slab phone. If you can stretch your budget, the Razr Ultra 2025 is the better flip. If you can't, this will do the job.
