❤ Samsung Galaxy Z Flip 4

Table of Contents



Another Samsung Unpacked event has come to pass, and this one brought us the fourth generation of foldable Galaxy smartphones. Quite expectedly, Samsung announced the fourquels of the Fold and Flip, the first being more like a foldable tablet, while the Flip – a nostalgia-sprinkled flip phone.






Today, we will be exploring the Samsung Galaxy Z Flip4, which is much like the Galaxy Z Flip3, but better. This is a formula that’s been in use for years now as the technology cannot advance as fast as makers are bringing a new version of their phones. But while the new Z Flip4 won’t make many (if any) Z Flip3 owners upgrade, it improves enough bits to make even more people think of getting this new foldable flagship.

Samsung has improved on the Galaxy Z Flip3 by tweaking all weak points both reviewers and users have agreed upon – low-light camera performance, battery life, charging speed. And, of course, the new Z Flip4 gets to boast the most current Android chip – the Snapdragon 8+ Gen 1.





The new Galaxy Z Flip4 features the same internal Dynamic AMOLED 2X and external Super AMOLED screens as the Z Flip3. But thanks to reduced bezels around the foldable screen and a flatter aluminum frame, the Z Flip4 is now a bit shorter and with a thinner hinge.

The Foldable Dynamic AMOLED 2X remains equally adaptive with up to 120Hz refresh rate and equally bright with a peak brightness up to 1200 nits. The crease in the middle is here to stay for now and so is the perforation for the selfie camera.

The Z Flip4 is IPX8-rated for water resistance – a feature that only Samsung offers across its third and fourth generation of foldable devices. Samsung and Sony are the only two makers that aim to offer water protection on most of their phones, and we truly appreciate the effort.

Besides the chipset upgrade, the Galaxy Z Flip4 also features an improved camera system on the back. It is still a dual-camera setup, but the main shooter now relies on a larger 12MP sensor with 1.8µm pixels coupled with a wider 24mm f/1.8 OIS lens. This new sensor should allow for a 65% improvement in light gathering and improve the low-light performance. The 12MP ultrawide and 10MP selfie cameras remain the same as on the Flip3.

The Galaxy Z Flip4 is powered by a 12% larger battery – it now packs a 3,700mAh cell, up from 3,300mAh within the Flip3. And even better, the phone now supports 25W fast charging, up from the sluggish 15W. The wireless fast charging has been sped up, too, now up to 15W.





And that’s about it – a new chipset, main camera, battery, and improved charging speed. And the latest Android version with the most current One UI, of course.

Going through the specs sheet, there is little missing – a zoom camera comes at the top of our head. The improved hinge should be fine for at least 200,000 cycles, and we appreciate the improved Gorilla panels and the tougher aluminum frame, even if by small margins.

Unboxing the Galaxy Z Flip4

The Galaxy Z Flip4 ships with an incredibly thin and lightweight box. It is lying open, face-down in there, waiting for its first user. A thin paper compartment houses the USB-C cable and the SIM ejector. And that’s all you will find.





There is no charger or case within the retail box, and if you don’t own Samsung’s 25W power adapter, it’s probably a good idea to buy one so you can use that fast charging.


The Galaxy Z Flip4 is a minor upgrade over the Flip3 even if it introduces some important improvements like a larger battery, faster charging, and better low-light performance for the main camera. We did appreciate the option to shoot in full resolution with the rear camera when taking selfies, too.





Obviously, these won’t make any Galaxy Z Flip3 user upgrade to Flip4. But by addressing most of the Flip3 concerns, Samsung has made the Z Flip4 an even more attractive and desirable offer.

The new Flip4 launches at €1080/$999, which is a flagship price, but not as high as €1800 like the Fold4. And for that, we’d consider it a reasonable price for features/money ratio.

There are a handful of foldable smartphones on the market, fewer even if we are to list foldable smartphones like the Flip and exclude foldable tablets like the Fold.

If you are keen on getting a phone like the Flip, but the price of the Flip4 does not fit your budget, you may want to consider the Galaxy Z Flip3 as it is now €400 cheaper than the Flip4. It is pretty much the same device with less inspiring battery life, charging speed and so-so low-light performance.

The recently announced Motorola Razr 2022 will launch any moment now in China, but we are not sure if it will make it to other markets yet. It is based on a 6.7-inch foldable screen, like the Flip4, but it’s got 1B colors and a 144Hz refresh rate. The chipset is the same, and the camera experience is similar. The Razr has an iconic form factor and a larger external display that allows for even more control while the phone is closed.





The rest of the foldable phones are rather large – like the €1800 Galaxy Z Fold4. It’s an all-powerful smartphone with one of the largest OLED screens on a smartphone and an under-display camera for video chats; it’s got a whole bunch of cameras, and the external display is as good as the market offers, large at that. If you don’t mind having a phone this thick (16mm) and heavy (263g), the Fold4 could be your next phone.

Xiaomi has recently announced its Mix Fold 2 – which is even thinner than the Fold4 with larger screens and Leica-powered camera setup. It has a sleeker design and charges faster, but for now, it’s a China-only device.

If you are eyeing the Flip4 because of its compact shape, you may also want to consider some of the compact bars that are available right now. Like the €700 Galaxy S22, which has a 6.2-inch Dynamic AMOLED 2X screen, powerful hardware, and its triple-camera on the back has a 3x telephoto.

The €800 Zenfone 9 is even smaller with a 5.9-inch 120Hz Super AMOLED screen, the most recent Snapdragon chipset, and a similar dual-camera that is capable of high-quality digital zoom though. The Zenfone 9 also offers outstanding battery life!

There is also the small iPhone 13 mini, which is the smallest flagship on the market based on a 5.4-inch screen. It is the most powerful small phone in the world right now, and the only major setback is the 60Hz OLED screen.

The Galaxy Z Flip went from a fashion-centric device to a full-blown flagship in just a couple of generations. The Flip4 is what the Flip3 should have been from the get-go – a powerful foldable smartphone with excellent camera performance, decent battery life and charging speed.





And indeed, we can say a lot of positive things about the new Z Flip4 – it has a superb water-proofed design that will hit the nostalgia notes across many users. It’s a compact flip phone, one that clicks simply great.

The Z Flip4 offers an excellent AMOLED screen, good battery life, good charging speed, and the speakers are nice. It also packs the most powerful Android chip to date, though the thermals lead to throttling.

Finally, the camera performance is superb across the board, photo and video, day and night.

We consider the Flip4 as the most affordable foldable smartphone of the current generation, and for its thousand euros, it delivers an outstanding set of features.





It’s not an ideal smartphone – it takes a while to get used to its design and form factor. Then you need to live with the crease and the plastic screen protector over the screen. Dust gets in various places, too.

Then there is the heavy throttling just after five minutes of peak loads. And there is no zoom camera.

While durability concerns remain with regular reports of bubbles forming under the screen protector along the crease, solid warranty coverage from Samsung has those reasonable fears taken care of.

The fourth generation Z Flip is moving the series into a bright future, and it does everything right with the technology it has at its disposal. We are recommending it to people who’d like to own a unique phone, small, and yet powerful and capable; to users that will take it with all of its good and not so good aspects.
