The Samsung Galaxy Z Flip series is the most successful foldable phone to date and the newest Galaxy Z Flip 4 aims to perfect a formula that has kept Samsung ahead of the competition. If you’re unfamiliar with the concept, the Z Flip 4 can be folded in half to become an extremely compact phone. Once unfolded, it’s about the size of a regular 6.7-inch full-featured Android phone.
Its pliable nature also allows it to be used partially folded. Its base becomes a “natural tripod” for photos or video calls. Some even hold it like a classic camcorder while recording video.
In this 4th iteration there are several important improvements that you should not miss, such as: B. the larger battery and better battery lifethe improved camera system, and the new computer platform. All three (and more) make this new version significantly better than the Galaxy Z Flip 3.
Our specific The Galaxy Z Flip 4 works with the AT&T network, where it retails for $27.78/month if you qualify. Compared to other models, there may be slight differences in antenna configuration and 4G/5G bands. However, both Sub-6 and mmWave technologies are supported, supporting excellent worldwide compatibility for travelers who may use data roaming.
The phone also comes preinstalled with AT&T specific software such as the AT&T Account Manager. There are those too AT&T Smart WiFi App for easy and secure connectivity in public spaces and on the Internet AT&T Remote Support This allows trained support staff to access the phone with your permission. Since the Galaxy Z Flip 4 isn’t geared towards power users, these two apps might come in handy for most people.
The new Z Flip 4 is based on a similar architecture as its predecessor. However, the hinge has been improved and the aluminum frame looks more premium. Also, the metal doesn’t catch fingerprints (can I have that on my fridge, please?). The glass back is a bit more resistant (Gorilla Glass Victus Plus), but please don’t drop it.
When closed, the phone occupies a compact 84.9 x 71.9 x 15.9mm and unfolds to 165.2 x 71.9 x 6.9mm. His weight of 187gr is comparable to phones occupying the same volume, and its metal and glass construction probably makes it a bit heavier than lower-end phones with more plastic.
The chassis is very stiff when closed, and “ruggedness” is an advantage of this design. it is hard to crack your primary screen by dropping the phone. The display is not only embedded inside the phone, but is also made of flexible materials and a soft protective layer. Samsung does that too waterproof (IPx8) foldable devices, including this one.
The hinge is firm and stays in place at virtually any angle you adjust it to accommodate different use cases. The downside is that you need two hands to open it. I’m not saying it’s impossible to open with one hand, but it’s too difficult.
The Z Flip 4 is very comfortable to hold, but the volume button is placed very high on the right, and you’ll likely use two hands to change the volume. Samsung may want to add a widget in the Edge Bar app.
Z FLip 4 audio quality
That’s a great transition to audio quality. The Z Flip 4’s speaker sound quality is excellent and comparable to other expensive phones, including the iPhone 13 Pro. The form factor of the Z Flip 3 introduces no compromises here.
Z Flip 4 experience
The compactness of the (folded) phone is exceptional when you keep the phone in a front pocket, whether in men’s or women’s jeans slightly loose pockets. The thickness of the phone might be a bit too big for very tight jeans and tight pockets, so you should know that depending on your dress style.
That Flex mode (partially unfolded phone) is very convenient and I mainly use it for watching videos or making video calls. As said, the base acts as a natural tripod and you’ll find yourself using it to look at your screen while doing something else with your hands (like taking notes).
Samsung even introduced Flex Mode controls for all apps, where you can force any app to only use the top half of the screen and leave the bottom half with controls like screenshots, brightness, and even a trackpad. Below is a screenshot showing how to choose which apps are enabled (check the Samsung’s Flex mode page for more).
When the phone is closed, there’s a small 1.9-inch cover “screen” that’s handy for checking notifications, but also for quick interactions via widgets to control basic settings (brightness, bluetooth, flashlight…) .
Samsung has a good number of widgets (weather timer, voice recorder…) but as a user, my favorite thing is to use the cover screen as a selfie camera. I highly recommend exploring the cover screen options to maximize the benefit for YOU.
I found a video that goes into pretty much detail about the cover screen features:
The Galaxy Z Flip 4’s OLED display supports refresh rates between 1 Hz and 120 Hz, depending on the situation. Everything happens automatically, but you benefit from longer battery life. Picture quality is impeccable, which is not surprising given that Samsung is leading the small OLED display market.
As usual with the Z Flip 3, the folding display has a crease that you can feel with your finger and, above all, see from the angle. My experience is that you usually don’t notice it and quickly forget it.
After all, all smartphone displays are largely reflective, so in practice it doesn’t look much different. If you are not sure, look at the display in a store to make up your own mind. That’s the best way and it’s up to you.
The display has a thin layer of flexible, glass-like material, but an additional layer of soft plastic provides extra protection for the screen. That’s great, but that soft layer is visible around the selfie camera and many people are tempted to peel it off. NOT.
At first the display seemed to be dark, but you can go to the display settings and Use the Extra Brightness option. to make it as bright as any other high-end phone. I can only assume it was battery optimization, but I like it when my screen is “extra bright”.
Galaxy Z Flip 4 camera
Samsung has greatly improved the Galaxy Z Flip 4’s rear camera system. It gets a Ubergizmo CAMERA HW score of 148 (vs. 117 on the Z Flip 3), so that’s a significant improvement that we think most independent reviews will agree with.
Samsung uses a better primary sensor with a 63% larger sensing area and large 1.8 micron pixels. The lens is still optically stabilized for maximum clarity in all situations.
The Z Flip 4 CAMERA HW score of 148 is slightly lower than the Galaxy Z Fold4 CAMERA HW of 155 and the Galaxy S22+ CAMERA HW of 154. The lack of a dedicated telephoto lens contributes to this gap, and no software update can provide a decent replacement be.
On the front, the 10MP selfie camera uses a tried and tested Sony IMX-374 sensor with an f/2.4 lens. Picture quality is good, even in low light, and that’s great for video calls. There are smartphones with much more powerful cameras, but the Z Flip lets you, too Take selfies with the rear camera and cover display.
The camera was a weak point of last year’s Galaxy Z Flip 3 and we’re happy to report that the Z Flip 4 offers much better photo capabilities, similar to the Galaxy S22.
Thanks to its Snapdragon 8 Gen 1+, the Z Flip 4 is capable of peak performance in everyday phone use. The processor runs at full speed for a few seconds, gets the job done and returns to a power saving state.
In this case, the full performance of the Qualcomm platform is constrained by the poor cooling performance of the phone. Simply put, it’s not designed as a gaming phone, but for everyday use you get all the top performance benefits of the Snapdragon 8 Gen 1+, but not the sustained speed that games or heavy apps require.
The benchmarks show this clearly, even if they don’t run that long. The Galaxy Z Fold 4 has the same chip but has significantly higher performance. The main difference between the two phones is their cooling ability. Over time, the Z Flip 4’s heat builds up much faster, limiting performance.
However, this speed remains very good for this size. In a future article we should compare it to the new Motorola RAZR 2022 powered by the same Qualcomm platform.
Battery life of the Galaxy Z Flip 4
The battery life of the Z Flip 4 is noticeably better three factors. First is the battery 13% larger (3700mAh vs 3300 before), which should extend the battery by at least that amount, but it’s getting better.
Second, the variable refresh rate from 1Hz to 120Hz also lowers power consumption. When watching a movie at 30 FPS, the display may adjust. And if you’re looking at a static image, the refresh rate could drop to 1Hz. That’s potentially a lot of power savings compared to running at constant 60Hz or 120Hz.
Finally, the Snapdragon 8 Gen 1+ is significantly more energy efficient than the Z Flip 3’s Snapdragon 888 processor. Less energy is consumed for the same work. The result is a Z Flip 4 phone that should get you through the day without stress.
If you need to charge that 25W wired charge is much better than the previous 15w charge. It’s far from the fastest (check the OnePlus 10T’s charging speeds), but it’s a lot better than the Z Flip 3.
The Samsung Galaxy Z Fold 4 is a significant update over its predecessor. Critical systems and features have been improved and the overall package between design, performance, battery life and camera has become great.
Should a Z Fold 3 owner upgrade? If you can afford absolutely yes! And if your budget is a bit tight, check out the various Samsung deals and trade-ins on the official website because Samsung is trying hard to get people to buy the latest devices.
The Galaxy Z Flip 4 is set to be the most popular foldable device of 2022, and I’ll likely use it as my main phone going forward (as I did with the Z Flip 3). Keep in mind that the user experience is different than your “standard” phone and the same budget would get you slightly higher specs with a classic Galaxy S22+ or higher.
Still, I know plenty of people who could have any phone and choose to use the Galaxy Z Flip series as their primary handset. This new Z Flip 4 will speed it up even more.
