Samsung Galaxy Z Fold4 unveiled
Design & Display
While the thinnest part of the Samsung Galaxy Z Fold4 is 14.2 mm, the thickest part is the hinge, 15.8 mm. when unfolded. The thickness is controlled at a mere 6.3 mm. It is still a heavy product, weighing 263 grams.
Both internal and external screens use the Dynamic AMOLED 2X material and both support a 120Hz high refresh rate. The minimum refresh rate of the external screen is 48Hz, but the internal screen can reach as low as 1Hz.
The outer screen is 6.2 inches with a resolution of 2316 x 904 pixels and an aspect ratio of 23:1.98. At the same time, the inner screen is 7.6 inches when expanded. It has a resolution of 2176 x 1812 pixels and an aspect ratio of 21.6:18.
The outer screen and the back cover of the fuselage are covered with Corning Gorilla Victus+ glass. Thus, we are dealing with the world’s strongest folding screen product. Also, due to the screen structure optimization, the durability of the inner screen has been improved. Now, it can effectively resist external impact damage. The frame and hinge cover is made of armored aluminum material. In effect, the whole machine has an IPX8 waterproof rating.
The internal screen has got some multitasking upgrades. The newly designed taskbar layout is similar to that of a traditional PC. So you can easily access frequently used and recently used apps.
There is also a new gesture shortcut split screen. So now, it can open the multitasking window more intuitively. Using gestures, you can switch the app from full-screen mode to pop-up view, or split the screen in two.
The S Pen stylus also comes with optimizations that make multitasking experience even more intuitive. It has a vertical protective case with an exclusive slot for easy use at any time.
Cameras
On the back of the phone, we can find three camera sensors. The main camera is a 50-megapixel ultra-wide-angle lens. It has a 23% more light input, OIS, 1.0-micron pixels, F/1.8 aperture, PDAF focus, and supports 3x optical zoom as well as 30x Space zoom. The second camera is a wide-angle lens with a 12MP resolution, 1.12 microns, and F/2.2 aperture. Finally, there is a 10MP telephoto lens, coming with OIS, 1.0 microns, F/2.4, and PDAF.
Now, the most interesting part. The top of the inner screen integrates an under-screen camera. The corresponding area adopts a new scattering type sub-pixel arrangement. The camera under the screen has a 4MP resolution and an F/1.8 aperture.
The external screen selfie camera has a 10MP resolution and comes with 1.22 microns and an F/2.2 aperture.
Inside, this amazing phone hosts the Snapdragon 8+ Gen 1 processor, 12GB memory, 256GB / 512GB / 1TB storage, and a 4400mAh battery. The latter still supports 25W fast charging. This might sound funny when calling a 25W output power a fast charging solution. But for Samsung, it is. It can charge about 50% of the battery in 30 minutes.
The phone leaves the factory with OneUI 4.1.1 / Android 12L onboard.
