Samsung Galaxy Z Fold 4 Review

The new Galaxy Z Fold 4 units the bar greater for all foldable and is probably the most superior, costliest Samsung Galaxy smartphone. On this fourth technology, Samsung brings an array of incremental however important upgrades we’ve got examined and analyzed utilizing our expertise with prior Galaxy Z Fold smartphones and a great information of the aggressive panorama.

Be aware: our particular unit is the AT&T Galaxy Z Fold 4 (mannequin SM-F936U) with 256GB of storage. AT&T sells it for $1799.99 (or $50/mo). Now we have the Black model, however the identical provider additionally has it in “Beige” and “Graygreen” which might be one of the best of the three.

This AT&T unit helps each mmWave and sub-6Ghz 5G connectivity, so you may get extraordinarily quick peak downloads the place mmWave is on the market, and the roaming compatibility appears to be extraordinarily excessive when you’re a world traveler. Choose carriers could discard mmWave assist of their items. Do your homework.

The standard AT&T safety apps, together with Name Shield and AT&T Cloud, supply free incoming calls and searching safety and really inexpensive cloud storage to their clients. That apart, the expertise needs to be similar to different Galaxy Z Fold 4 telephones.


The Z Fold design is likely one of the most intricate smartphone designs in the marketplace and has objectively been years forward of the competitors. As of immediately, the Galaxy Z Fold 4 design units a brand new bar and progresses in key areas: cowl display, digicam, and sturdiness.

The cowl display is 3mm wider, which is vastly essential as a result of, as a main telephone, it’s possible that you simply’ll use the duvet display extra usually than the first folding show. Basically, this makes it a extra traditional smartphone expertise though it’s nonetheless narrower. Samsung has barely modified the show ratio, and the brand new Z Fold 4 shouldn’t be as tall because the Z Fold 3, which is nice.

This 3mm achieve was acquired because of a extra optimized hinge design. The brand new hinge doesn’t protrude as a lot, and that’s how the left cover-screen bezel measurement was lowered.

Within the again, the Digital camera bump is a bit taller as a result of the digicam system has been modified to higher match the Galaxy S22/S22+ efficiency. This is likely one of the most anticipated adjustments, and that’s a great cause for the bump to be bigger.

Some folks freak out when the telephone wobbles a bit if used on a flat floor, but it surely’s by no means been a problem for us, particularly as a trade-off for a high-performance digicam. Packing an important digicam in a skinny telephone is bodily inconceivable with no sizeable digicam bump.

The Galaxy Z Fold 4 is waterproof (IPx8, so not dust-proof), and Samsung stays the one folding telephone OEM that produces a water-tight machine. It additionally has an 88% market share within the foldable telephones house and makes use of its first-mover benefit very nicely.

These three areas apart, the economic design function extra minor adjustments corresponding to a extra sturdy exterior glass floor (Gorilla Glass Victus+) much like the S22 Extremely or a practically invisible selfie digicam below the folding display.

The chassis is extraordinarily inflexible. Closed, it gained’t bend or shear below robust forces. The inner show is extraordinarily nicely shielded from drops onto laborious surfaces, however do not forget that the duvet show is sort of a traditional smartphone and may crack.

The Energy button doubles as a fingerprint reader on the fitting facet. It is sensible because it must work when utilizing both display. technique is registering just a few fingers to accomodate each attainable grip (we famous three).

The audio high quality is great, and nominal loudness apart, it’s higher than many laptops we’ve examined up to now. The sound is highly effective and clear, making the Z Fold 4 an important desk companion for watching TV reveals or video information whereas engaged on a pc.

Folding Expertise

The foldable design incorporates a radically totally different expertise vs. traditional telephones or bigger tablets. General, it feels similar to what we had final yr, however for individuals who are simply getting , there are highlights you shouldn’t miss.

To begin with, the 7.6″ OLED show brings a vastly superior visible expertise for consuming content material typically. textual content, web sites, video games, movies, and pictures are a lot better represented, and that’s the basic cause why persons are prepared to spend that a lot.

The Flex Mode (folded at ~90 levels) helps you to naturally relaxation the telephone on a flat floor to look at movies, take part in video calls, and even take pictures. It may be extraordinarily handy and is basically a pure tripod.

The big show brings a world-class pill expertise in a distinctive pocketable format. The Galaxy Z Fold telephones are simply beginning to get some competitors and are undoubtedly the 7.6″ Android pill with one of the best efficiency/measurement or efficiency/weight ratio.


The Z Fold 4 retains the “world’s most efficient telephone” title within the household. Samsung has refined the split-screen expertise, making it simpler to open a number of apps concurrently. Having two vertically cut up apps is the best choice for us, however Samsung helps as much as 4 tiles + 1 floating app.

There’s ample room on the display, so Samsung’s newest One UI 4.1.1 provides the Android 12L taskbar on the backside, letting you turn to the newest or your favourite apps with out going again to the house web page.

On prime of that, it helps an non-compulsory S-Pen digitizer which takes the entire thing to the following degree for individuals who like taking notes, making sketches, or doodles. The S-Pen can even grow to be a distant management for displays or pictures. The competitors is left within the mud.

The show crease within the center can generally be felt when writing with the S-Pen. It’s no massive deal; it’s best to test for your self in a retailer. What’s slightly extraordinary is to have this selection in any respect. It could be great if Samsung might combine the pen into the chassis sometime.

Show(s) high quality

Technically, each shows function unimaginable picture high quality and luxury and may go from 1Hz to 120 Hz for optimum energy consumption. You get butter-smooth scrolling or gaming once you want, and save energy once you don’t.

Key numbers: 940 NITs (handbook setting, measured), 1200 NITs (peak brightness specs, auto-mode) , dE2000 of 1.0 (glorious colour accuracy, in “pure” mode)

Samsung has made delicate adjustments within the facet ratio, which is great as a result of it improves the proportions of the handset, but it surely doesn’t have an effect on how the telephone feels or is used vs. the Z Fold 3.


The 4MP selfie digicam below the folding show is very nicely hidden and practically invisible. Samsung engineers have doubled the pixel density on prime of the digicam, and also you might need to squint to identify it. That mentioned, it additionally appears to barely lower the picture high quality as a result of it does block among the incoming mild.

There’s no must delve into all of the technical particulars, as this Samsung OLED show’s capabilities are past what your eyes can understand and are among the many finest immediately’s know-how can produce.

Digital camera Efficiency

The Galaxy Z Fold 4 brings has a digicam efficiency akin to the Samsung Galaxy S22 and S22+, among the finest in the marketplace. Within the rear, there are three cameras:

  • 15mm 13-MP f/2.2
  • 23mm 50-MP f/1.8 (Main) +OIS
  • 62mm 10-MP f/2.4 +OIS

There are additionally two selfie cameras

  • 25mm 10-MP f/2.2 (punch-hole within the cowl show)
  • 30mm 4-MP f/1.8 (below the foldable show)

Our algorithmic CAMERA HW rating ranks the Galaxy Z Fold 4 (rating=155) on the similar degree because the Galaxy S22+ (rating=154), a wonderful rating as unbiased reviewers acknowledge the S22+ as an excellent shooter within the high-end phase.

The Z Fold 4 new GN3 main sensor is ~26% bigger, which is critical, however the sensor pixels are smaller than the Z Fold 3 (50MP 1.0 microns vs. 12MP 1.8 microns). Be aware that smaller pixels additionally lower the sunshine seize effectivity. Moreover, we estimate there’s 17% extra mild attending to that bigger sensor, so positive factors won’t be as dramatic because the sensor measurement alone suggests, but it surely’s a constructive change.


The Samsung GN3 sensor is extra versatile and adaptable to totally different scene circumstances. Extra importantly, Samsung engineers have extracted each little bit of high quality from it. For instance, if there’s ample mild, Samsung is likely one of the uncommon OEMs to supply a full-resolution 50 Megapixel seize in “auto” mode that ought to yield extra particulars. 

The brand new 3X optical zoom digicam can also be barely higher, with a 62mm lens vs. the earlier 52mm one. The distinction is slight, but it surely’s price nothing. For reference, the 10X optical long-zoom of the S22 Extremely is a 230mm zoom.

The higher selfie digicam is on the duvet display, which is sensible since you seize selfies with one hand. The 4MP selfie digicam is for video calls (+Flex Mode), and that exercise is principally restricted by community connectivity, so 4MP is sufficient.

System efficiency

Because of the Snapdragon 8+ Gen 1, the computing efficiency of the Galaxy Z Fold 4 is with out reproach, with excellent CPU velocity. With such a display, graphics efficiency is much more important. In our assessments, it was as much as 82% sooner and on par with the Galaxy S22 Extremely.

In “stress assessments” like 3DMark Wildlife excessive, this smartphone confirmed glorious cooling capabilities and can be a powerful gaming telephone. That aligns with Samsung’s objective of constructing a productiveness and multimedia champion, and customers may be assured they’re getting one of the best degree of Android efficiency in 2022.

Battery Life

The 4400 mAh battery capability is equivalent to final yr’s Z Fold, and it’s regular since it’s restricted by the chassis measurement, which is 2% smaller than its predecessor. That mentioned, it does have longer battery life, and our expertise means that it could possibly be as a lot as 20% greater relying in your exercise.

Two optimizations might induce such a spot: the variable show refresh charge and the upper energy effectivity of the brand new Snapdragon 8 Gen 1 platform. Nonetheless, the bigger show and smaller battery (vs. the S22 Extremely) means the battery life is shorter than an everyday telephone, maybe barely above a full day’s work for most individuals. 

The charging velocity was additionally barely improved however pales in comparison with current telephones from OnePlus, Infinix, and others. Since battery capability is unlikely to transcend 5000 mAh any time quickly, charging velocity is the brand new battleground.


The Samsung Galaxy Z Fold 4 is a technological marvel that is still approach forward of the competitors regardless of a lowering tempo of innovation. It has grow to be the de-facto finest folding telephone on the earth, offering the finest visible expertise, productiveness, and glorious sturdiness.

These info alone would qualify it as your foldable telephone of selection when you made a purchase order choice. That mentioned, it’s (sadly) not for everybody, and proudly owning a folding telephone stays a really totally different smartphone expertise that could possibly be thought-about fastidiously.

To the fitting viewers, the Z Fold 4 brings an unparalleled expertise that explains why this class grows very quick, even with the $1799.99 begin value.
