The cowl display is 3mm wider, which is vastly essential as a result of, as a main telephone, it’s seemingly that you simply’ll use the quilt display extra typically than the first folding show. Primarily, this makes it a extra basic smartphone expertise regardless that it’s nonetheless narrower. Samsung has barely modified the show ratio, and the brand new Z Fold 4 just isn’t as tall because the Z Fold 3, which is sweet.

This 3mm acquire was acquired due to a extra optimized hinge design. The brand new hinge doesn’t protrude as a lot, and that’s partially how the cover-screen’s left bezel measurement was decreased.

Within the again, the Digicam bump is a bit taller as a result of the camera system has been modified to raised match the Galaxy S22/S22+ efficiency. This is likely one of the most anticipated modifications, and that’s an excellent purpose for the bump to be bigger.

Some folks freak out when the telephone wobbles a bit if used on a flat floor, nevertheless it’s by no means been a problem for us, particularly as a trade-off for a high-performance camera. Packing an amazing camera in a skinny telephone is bodily not possible with no sizeable camera 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 characteristic extra minor modifications similar to a extra sturdy exterior glass floor (Gorilla Glass Victus+) much like the S22 Extremely or a almost invisible selfie camera below the folding display.

The chassis is extraordinarily inflexible. Closed, it received’t bend or shear below robust forces. The inner show is extraordinarily nicely protected against drops onto laborious surfaces, however keep in mind that the quilt show is sort of a basic smartphone and might crack.

The Energy button doubles as a fingerprint reader on the suitable aspect. It is smart because it must work when utilizing both display. A superb technique is registering a couple of fingers to accomodate each doable grip (we famous three).

The audio high quality is superb, 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 amazing desk companion for watching TV exhibits or video information whereas engaged on a pc.

Folding Expertise

The foldable design encompasses a radically completely different expertise vs. basic telephones or bigger tablets. Total, it feels similar to what we had final 12 months, however for many 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 on the whole. textual content, web sites, video games, movies, and pictures are significantly better represented, and that’s the basic purpose why persons are prepared to spend that a lot.

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

The massive 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 the very best efficiency/measurement or efficiency/weight ratio.


The Z Fold 4 retains the “world’s best 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 most suitable 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 latest or your favourite apps with out going again to the house web page.

On prime of that, it helps an elective S-Pen digitizer which takes the entire thing to the following stage for many who like taking notes, making sketches, or doodles. The S-Pen also can turn out to be a distant management for shows or images. The competitors is left within the mud.

The show crease within the center can typically 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 might be great if Samsung may combine the pen into the chassis sometime.

Show(s) high quality

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

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

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


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

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 greatest in the present day’s technology can produce.

The Z Fold 4 new GN3 main sensor is ~26% bigger, which is important, 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 gentle attending to that bigger sensor, so features won’t be as dramatic because the sensor measurement alone suggests, nevertheless it’s a optimistic change.


The Samsung GN3 sensor is extra versatile and adaptable to completely different scene situations. Extra importantly, Samsung engineers have extracted each little bit of high quality from it. For instance, if there’s ample gentle, 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 higher selfie camera is on the quilt display, which is smart since you seize selfies with one hand. The 4MP selfie camera is for video calls (+Flex Mode), and that exercise is principally restricted by community connectivity, so 4MP is sufficient.

System efficiency

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

In “stress assessments” like 3DMark Wildlife excessive, this smartphone confirmed wonderful cooling capabilities and could be a formidable gaming telephone. That aligns with Samsung’s objective of constructing a productiveness and multimedia champion, and customers will be assured they’re getting the very best stage of Android efficiency in 2022.

Battery Life

The 4400 mAh battery capability is an identical to final 12 months’s Z Fold, and it’s regular since it’s restricted by the chassis measurement, which is 2% smaller than its predecessor. That stated, 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 may induce such a spot: the variable show refresh price 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.

z fold4 charging speed

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