The Galaxy Z Flip 4 is less an innovation and more of a refinement of last year’s model. It sports slimmer bezels and flatter edges to make for a more premium-feeling device. Even with that, it’s still a fun little phone. Samsung is really leaning into the young crowd with the content creation features and general vibe of the handset, leaving the “mature” and “professional” look for the Galaxy Z Fold 4.
But I could say the same for the Galaxy Z Flip 3. It was also a fun phone, but with heaps of improvements over its predecessor including a radical redesign. So what makes the Galaxy Z Flip 4 stand out? To be perfectly honest, so far, not so much.
Refinement is the name of the game this year, almost to a disappointing degree. Samsung did boost the cameras a bit by using a brighter main sensor for better low-light photos. But the ultrawide remains the same and, while I’m still conducting my full testing, my first impressions are that the Galaxy Z Flip 4’s cameras perform practically the same as the Galaxy Z Flip 3’s — that is to say, not on the level of what you would expect from a $999 phone.
As you’ll see this Galaxy Z Flip 4 review in-progress, I find myself rather neutral about this phone. It’s not the upgrade I wanted to see over last year, but it’s certainly not a bad phone, either. I will update this over the coming days as I finalize my impressions and get test results in.
When you’re done here, make sure you read our thoughts on the Galaxy Watch 5, Galaxy Watch 5 Pro and Galaxy Buds 2 Pro as well to get a full picture of Samsung’s latest releases.
Samsung Galaxy Z Flip 4 review: Price and availability
You’ll be able to buy the Galaxy Z Flip 4 from Samsung or other retailers and carriers from August 26. If you’ve already made your mind up, you can pre-order the phone now from Samsung to get a free storage upgrade and a Silicone Ring Case or Strap Case to put it in.
The Galaxy Z Flip 4 starts at $999/£999 with 128GB of storage and 8GB of RAM, the same as last year for U.S. customers, but a touch more for U.K. buyers. You can pay extra for a 256GB model ($1,059) or the new 512GB model ($1,179) if you want some more storage room, but that’s the only difference.
Samsung Galaxy Z Flip 4 review: Design
From the outside, the Galaxy Z Flip 4 hardly looks any different. If you love the clamshell foldable design, you’ll probably be OK with this. The phone fits perfectly in my pocket without sticking out like the best big phones do.
Like last year, Samsung has provided a diverse slate of color options for the Galaxy Z Flip 4. There’s the Graphite option if you want something sensible, but you could opt for the more lively Blue, Pink Gold or Bora Purple options.
If you look a little further, however, you’ll notice that the Galaxy Z Flip 4 has flatter edges this year. They’re glossy unfortunately, and thus slippery, but they still manage to add some nice grip to an already ergonomic phone. The camera module sticks out a bit more on this model, possibly because of the new main 12MP sensor.
Samsung touted the slimmer and lighter hinge, though the Galaxy Z Flip 4 still has a very noticeable hinge gap when the phone is closed — this is the gap between the two displays at the hinge when folded. I had hoped for a gapless design like the Oppo Find N, as rumors suggested, but it seems Samsung wanted to focus more on the hinge weight and bulk rather than the gap.
The 1.9-inch cover display remains, offering you useful information and access to things such as Samsung Wallet or SmartThings. Opening the phone, I immediately noticed the slimmer bezels. The Galaxy Z Flip 3 had some pretty large ones, so the Galaxy Z Flip 4 looks a lot cleaner and more modern.
The side-mounted power button also doubles as the fingerprint sensor like last year, and I continue to find its placement awkward and unnaturally high. Don’t get me started on the volume rocker, which is near the top of the upper half’s right side. The fingerprint sensor itself is very quick once you place your finger properly.
The Galaxy Z Flip 4 didn’t revolutionize the design like the Galaxy Z Flip 3 did. This generation very obviously focuses on small improvements.
Samsung Galaxy Z Flip 4 review: Displays
On the inside, the Galaxy Z Flip 4 sports a 6.7-inch Super AMOLED display with a 1080p resolution and an adaptive 1-120Hz refresh rate. Out of the box, it’s deeply saturated in the characteristic Samsung way — gotta show off the AMOLED’s color capabilities. The cover screen measures 1.9 inches and it’s also a Super AMOLED. This is great for if you have a photo for your wallpaper on that little panel.
We haven’t gotten the Galaxy Z Flip 4 in for display testing yet, so I’ll report back with those numbers when I have them. But the displays are very nice with really punchy colors and excellent viewing angles. Watching the trailer for Blade Runner 2049, for example, was a wonderful experience with the neons and harsh orange tones. Even the trailer for The Rings of Power looked good on this screen, even if the show itself does not.
While I walked around testing the cameras, I could easily see the Galaxy Z Flip 4 in the intense Virginia summer sunlight. We’ll need to wait to see the level of brightness we measure in our lab, but I think it’s going to come out higher than average, much like the Galaxy S22 did.
The display crease, or the joint where the two displays meet, remains with the Galaxy Z Flip 4. Unfortunately, it also remains rather prominent. You can see it in most circumstances and feel it every time you slide your finger over it. I had hoped that Samsung would have figured out a way to address this with the Flip 4, but that doesn’t seem to be the case. I don’t like it any more than I did with the Galaxy Z Flip 3.
Samsung Galaxy Z Flip 4 review: Cameras
While I finish completing my camera analysis with the Galaxy Z Flip 4, I have some early thoughts and impressions. In my testing thus far, the Flip 4’s camera performance looks remarkably similar to the Galaxy Z Flip 3’s. I don’t see the refined Samsung post-processing that you’ll find on the Galaxy S22 series.
Instead, I have a lot of over-saturated, overexposed pictures that, when compared to my iPhone 13 Pro Max, don’t look all that great. Many of the colors in the shots I’ve taken up to this point are way over done, blinding in some places.
For example, I have a photo of some very colorful books in my house and the end result with the Galaxy Z Flip 4 disappoints me greatly. Compared to something like the iPhone, exposure and color correction are sorely lacking.
I haven’t gotten a chance to test low-light photography yet, so we’ll see if Samsung’s Nightography and brighter main camera sensor will pay off. Based on how the camera testing fares so far, however, I do not have high hopes.
Samsung Galaxy Z Flip 4 review: Performance
A new year equals a new chipset. Samsung went with the latest silicon from Qualcomm, the Snapdragon 8 Plus Gen 1, to power the Galaxy Z Flip 4 along with 8GB of RAM. We’ve tested this chip previously in phones like the Asus Zenfone 9 and found it to be a powerful option. While its CPU functions don’t serve as that much of an upgrade over the Snapdragon 8 Gen 1 (which the Galaxy S22 uses), the GPU saw some major improvements.
We haven’t run the Galaxy Z Flip 4 through our usual suite of benchmarks just yet, so I’ll come back when I have those results. In my personal use thus far, however, the Flip 4 flies through every task, even intense games like Genshin Impact. 8GB of RAM seems low nowadays when we have gaming phones with 16GB or 18GB, but I found it more than sufficient in my use.
Samsung Galaxy Z Flip 4 review: Battery life and charging
Samsung listened to criticisms about the Galaxy Z Flip 3’s battery life, which underwhelmed me in the best of circumstances. In the Tom’s Guide battery life test, the Flip 3 went for just 5 hours and 43 minutes in its default adaptive refresh rate mode. That’s by far one of the worst results I’ve seen in a long time.
The Galaxy Z Flip 4 got a battery capacity bump from 3,300 mAh to 3,700 mAh. That extra 400 mAh doesn’t seem like much to be frank, but we’ll have to wait to see how the Flip 4 does in our battery life test. At least the charging has jumped to 25W this year, but you don’t get a charger included in the box.
So far in my time with the Galaxy Z Flip 4, I’m not so hopeful. In just a couple of hours, it has dropped roughly 15% while sitting mostly idle. Granted, it had to get through setup and some simple photography, but it’s seen not a whole lot of use. Other phones barely lose a few percentage points with the same amount of work.
I will update this review when battery life numbers come in.
Samsung Galaxy Z Flip 4 review: Software and special features
The Galaxy Z Flip 4 ships with OneUI 4.1 over top of Android 12. For the most part, it’s similar to what you get on the Galaxy S22, but that’s not the whole story. The Flip 4 gets access to several features specific to it. The highlight of these is Flex Mode, which takes full advantage of the folding displays.
Flex Mode engages when you partially fold the Galaxy Z Flip 4, such as at a 45- or 90-degree angle. Your current app will split, putting the main functionality on the upper half and additional options on the bottom. There’s even a new trackpad feature, helping you navigate apps faster and easier.
Last year, the best examples of this were the Camera and YouTube apps. In the former, you could get all of the shutter controls and options on the bottom half of the phone while the top operated as the viewfinder. With YouTube, you could watch a video on the upper half and browse comments or suggested videos on the bottom much more efficiently than a standard smartphone.
However, Samsung has set its sights on the creative crowd, with the Galaxy Z Flip 4’s Flex Mode offering many options for things like Instagram Reels, TikToks, videos and vlogs, and more. While most of this is lost on me, I think all of it might convince more people to try the Galaxy Z Flip 4 for themselves.
OneUI 4.1 is a heavily-modified version of Android, far from Google’s vision. It has a lot of features, such as themes and a smorgasbord of options. The Galaxy Z Flip 4 also has additional options for the cover screen, which has gotten a lot more useful this year. Not only does it show basic info like the Galaxy Z Flip 3 did — such as notifications, battery percentage, weather, and the camera viewfinder — but you can also add more widgets and set a custom background (photo or GIF).
I liked having the calendar widget, too, which let me see my meetings and assignments for the day right from the cover screen. I imagine the music controls would also be handy, though I didn’t have a chance to listen to any tunes during my limited time with the Galaxy Z Flip 4. If you’re a SmartThings user, there’s also a new widget for home controls.
The Galaxy Z Flip 4 lets you reorder the cover screen widgets and choose from many clock faces, showing that Samsung wants you to make the Galaxy Z Flip 4 unique to you. This plays into the beauty of Android’s customization strengths.
Finally, the Galaxy Z Flip 4 enjoys Samsung’s top-tier update policy. That means the Flip 4 will see four years of platform updates (Android 16) and five years of security patches (2027). That means the Galaxy Z Flip 4 will go for longer before you need to upgrade — at least software-wise — which plays into Samsung’s admirable environmentally conscious initiatives.
When it comes to recommending the best Android phones for longevity, Samsung, with its excellent update policy, is one of my default choices.
Samsung Galaxy Z Flip 4 review: Early verdict
The Galaxy Z Flip 4, much like the Galaxy Z Fold 4, doesn’t have a huge suite of changes. This year, Samsung focused on incremental improvements, such as the new hinge design and slightly larger battery. The flatter edges refine the look, and the new chipset makes this one powerful little phone.
However, my early thoughts thus far have left me feeling unsure about the Galaxy Z Flip 4. I won’t settle on a rating until I have all of the data present, but I wouldn’t call this phone extremely good nor would I call it bad. For $999, it seems to have some drawbacks. The cameras, for example, do not live up to other similarly-priced handsets, at least in my early testing.
Don’t get me wrong, the Galaxy Z Flip 4 is a fun device, but I noticed that the Galaxy Z Flip 3’s novelty wore off pretty quickly last year. I’m concerned the same will hold true this time around.
Be sure to check back in the coming days as I update this review with our test results and camera comparisons.
