Samsung worked on the design problems of the previous Fold 3 and tried to reduce them in order to provide a better experience .. But in general, if you look at the Z Fold 3 and Z Fold 4 from afar, you will not be able to differentiate them from each other.
Samsung made the hinge stronger, thinner, and lighter.. so that the mobile phone is lighter, and its width is also the least simple thing.. but the mobile phone is still a bit big in the hand.. and it is heavy in the pocket because it weighs 263 grams.
The advantage is that you take a mobile phone and a tablet at the same time.. Also, the mobile phone is directed to a specific group.. Of course, there is no talk about the materials, all of them are premium materials with an IPX8 water and dust resistance certificate, and a Gorilla Glass Victus protection layer on the entire mobile.
the screen :-
The external screen is 6.2 inches in size.. and its display dimensions are more correct, and this is an attempt by Samsung to make the external screen more usable..or you can use the mobile with one hand.
The external screen is still of good quality.. Its type is Dynamic AMOLED X2, with a frequency of 1 Hz to 120 Hz.. and the screen is better to use than the previous Galaxy Z Fold 3.
As for the internal screen, it is a 7.6-inch Dynamic AMOLED X2 with a frequency from 1 Hz to 120 Hz .. with a hole for the selfie hidden under the screen. If you focus, you will see it, but in general it is not clear and you will take the full screen experience.
The screen of the Galaxy Z Fold 4 is better than the Galaxy Z Flip 4 by many stages.. The experience of watching videos is excellent, but the location of the screen hinge is still noticeable and tangible when you reach for it.
The advantage here is that the hinge of the screen is heavy, durable, and clearly drier than the previous generation.. to the point that you can let the screen fix it at any angle you like.
the performance :-
The mobile comes with a Qualcomm Snapdragon 8+ Gen 1 processor with 4 nano technology and supports fifth generation networks. The performance of the mobile is impressive.. very fast and there are no crunches or any cutting.
The software is modified and largely customized for mobile phones.. The most important addition is the taskbar that makes your use of the tablet easier.. Navigating between applications is done in a missile way.. There are visible programs and the latest programs that I used, and also in the menu tab so that you can open another application easily without exiting.
You can also split screen and open 3 programs together on the big screen.. If you want more than 3 programs, you will open more programs than pop up and move them around the screen easily and open them at any time.
If you would like to turn off the large screen and return to the external screen, it will show you options to choose between. What do you want to do.. If you want to complete what you are doing from the external screen or turn it off.
There is also the Flex Mode that turns the mobile phone into a laptop..by making the hinge an angle of 90 degrees and you can put the mobile phone on the desk in front of you and write on the keyboard with the screen in front of you above..or you can clear the space under the Touchpad and control the content above.
Safety and other factors:
The fingerprint is located on the power button, and you can remove it with a touch or a step.. It is very fast and practical.. You have 4 microphones in the mobile phone, so that when you enter a meeting, your voice is clear, isolated, and sweet.
The sound of the mobile phone is awesome..the loudest stereo sound you will get from a Samsung mobile..a sound that really suits the size and power of the mobile.
As for Wi-Fi networks, it is the simplest thing from the Galaxy S22 Ultra.. but it is still not the best network out there.
the battery :-
The same old 4400 mAh battery.. but the processor is more efficient.. the external screen has been reduced to 1 Hz to save on consumption.. the software itself has become smarter.. you can say that performance has improved by 15%.
The same 25-watt slow charger that will charge the battery in about an hour and a half, and it supports 15-watt wireless charging.
Cameras:
The mobile phone has 5 cameras .. 3 in the back, of which the main one is 50 mega-pixels with an F / 1.8 lens slot with optical stabilization, the second with a 10 mega-pixel camera with an F / 2.4 lens slot with an optical stabilization dedicated to 3X zoom and connects to 30X software .. the third is 12 mega-pixels with aperture lens F/2.2 for wide photography.
A 4-megapixel selfie camera under the internal screen, with an F / 1.8 lens slot .. and a 10-megapixel selfie camera with an F / 2.2 lens slot on the external screen.
The camera is excellent.. It offers you a delicious look, and the sharpness is very reasonable.. The performance is very close to the Galaxy S22 Ultra, taking into account the increased details in favor of the S22 Ultra.. When I tried the zoom, I found that it was very good in the Z Fold 4 compared to the S22 Ultra, except for more details and a larger range in the zoom.
Shooting in indoor lighting, if you do not turn on the Night Mode, you will find most of the pictures close to each other.. but the details of the Z Fold 4 are the least simple thing about the S22 Ultra.. and when you turn on the Night Mode, the performance improves a lot.
As for the selfie, there are 3 ways for the selfie.. The easiest is the external selfie, which is better than the selfie under the internal screen.. As for the most difficult method, it is that you turn on the external screen and photograph with the rear camera.
When I compared the selfie with the S22 Ultra, I found that the external selfie in the fold performed less.. But when you take a selfie with the rear camera, it will give you an excellent look.. I can't say that it is better than the S22 Ultra, but it is excellent.
When the lighting decreases, you can take a selfie in Night Mode with the rear camera, and this provides an excellent experience that is much better than the S22 Ultra.
As for shooting videos, the mobile phone can shoot up to 8K at 24 frames per second..and of course the mobile phone has an additional microphone for noise isolation..and the main camera and zoom lens have an optical stabilizer.
Final opinion:
The Galaxy Z Fold 4 mobile phone is not for anyone .. Even if the money does not make any difference with you and your use does not have a lot of multi-tasking and you do not need this large screen .. I think you should buy the S22 Ultra or iPhone 14 Pro Max better.
