Samsung Galaxy Z Fold 4 vs. Samsung Galaxy Z Fold 3

Samsung Galaxy

The upcoming Samsung Galaxy Z Fold 4 foldable phone builds on the solid foundation established by last year’s Z Fold 3. That was the first foldable phone we recommend without reservations about the build quality.

On the outside, it appears to be very similar, perhaps more refined, but it follows the same blueprint. This means that the phone has a smaller “Cover Screen” on the front, but you can unfold it to reveal the larger, nearly tablet-sized main display. This year, Samsung allegedly perfected the hinge, reduced the crease in the middle of that big screen, and improved the performance and camera of the Z Fold 4.

Following the difference Between Samsung Galaxy Z Fold 4 and Samsung Galaxy Z Fold 3

Quality of Design and Display

While Fold 4 and Fold 3 may appear to be very similar, closer inspection reveals significant differences. The most notable difference is that Samsung Galaxy has managed to conceal the hinge, making the Fold 4 appear more compact. Additionally, the phone is expected to be lighter by nearly 6%! The new Fold will weigh 254 grams, compared to 271 grams for the previous generation, and will be very close to your typical Max or Ultra-sized regular phone at this weight. This style of a foldable phone is quite heavy, so seeing an improvement in this area is fantastic.

According to rumors, Samsung is making significant efforts to make the next Fold even slimmer. According to reports, a new “single” hinge has been developed that is much less bulky than the one used in the Z Fold 3.

Rumors differ on biometrics, but we’d expect the fingerprint scanner to remain embedded in the power button on the side. That worked well on the Z Fold 3, and we don’t expect Samsung to change it.

Software and Performance

Given the premium price, it’s not surprising that the Fold 4 has only high-end components under the hood.

The Snapdragon 8 Gen1+ processor will be available to all buyers, regardless of country, on the Z Fold 4. This is fantastic news for those in the UK and Europe, where Samsung GalaxyS series flagships typically get the less powerful Exynos processor, but not with the fold.

This is an improvement over the Snapdragon 888 chip used in the Fold 3. Both the Fold 4 and Fold 3 have 12GB of RAM and a generous 256GB of onboard storage (no microSD card support here). One small detail: the new model’s storage is UFS 4.0, which provides significant speed and efficiency gains. UFS 4.0 has twice the bandwidth of UFS 3.1, with up to 23.2Gbps per lane. According to Samsung, UFS 4.0 is “ideal for 5G smartphones that require massive amounts of data processing.”

The Z Fold 4 is expected to ship with Android 12 but will be updated to Android 13 shortly after launch. Samsung has committed to providing four major software updates and five years of security updates to most of its devices, which is great news for both of these phones.

The most exciting new software feature coming to the Fold 4 is “swipe for split screen,” which is self-explanatory and will make multitasking a breeze.


The Fold 4 is expected to adopt the new camera styling seen on the S22 Ultra, with each camera lens protruding from the back of the phone.

The Fold 4’s rear cameras include a 50MP main shooter, a 12MP ultra-wide lens, and a 10MP 3X telephoto lens. That is a slight improvement over the Fold 3’s triple camera system, which included a 2X zoom camera and a 12MP main shooter. Unfortunately, Samsung does not include a periscope zoom lens, which is a distinguishing feature of the S22 Ultra.

Haptics and Audio Quality

The Fold series has always had some of the most impressive loudspeakers on a smartphone, most likely due to the larger form factor, which gives the speakers more room to shine. We’re curious to see if the Fold 4 improves audio quality, but we haven’t heard anything concrete yet.

The Fold 4 and Fold 3 do not have a headphone jack, but this is standard on most modern phones.

We still don’t know much about the Fold’s vibration motor, but we will update this section as soon as more information becomes available.

Charging and Battery Life

One thing that hasn’t changed in the Fold 4 is the battery size, which will be the same 4,400mAh cell as the previous year’s model. In our experience, this worked perfectly, so we are not disappointed.

The Fold 3 has a maximum charging speed of 25W, and Samsung may give us faster, 45W charging speeds to match the rest of its high-end phones, but there has been no official word on that.

Wireless charging should be available on both the new and older-generation Folds.
