Samsung Galaxy Z Fold 4: Everything You Need to Know + How to Unlock 🔓

Samsung has embraced the idea of evolution over revolution when it comes to folding technology. While the Samsung Galaxy Z Fold 4 basically fuses the formfactor of a Z Fold, the standard which very much follows in the footsteps of its predecessor. 

The Samsung Galaxy Z Fold 4 will start at $1799 and come in 128GB to a whopping $2159 1TB models. That’s the same starting price as its predecessor, which is a decent baseline. For the Galaxy S21, it hit the sweet spot of offering flagship specs for a reasonable price, and Samsung clearly seems to agree.

The Galaxy Z Fold 4 offers nothing close to the zooming experience you find on Samsung’s Galaxy S Ultra smartphones. All of them have a maximum of 100x digital zoom, though optical zoom varies a bit. The Galaxy S20 Ultra featured a mix of optical and digital zoom past 4x magnification, while the Galaxy S21 Ultra and S22 Ultra feature separate 3x and 10x optical zoom cameras, once again for a maximum of 100x zoom.

Still, the Galaxy Z Fold 4 brings an upgrade in camera zoom, even if it isn’t as good as what you find on the Galaxy S Ultra smartphones. The main camera has also been upgraded – it is now a 50MP sensor instead of a 12MP sensor, the same one that is featured on this year’s Galaxy S22 and S22+. A 12MP ultra-wide camera is also present on the rear.

For selfies and video calls, the cover display features a 10MP camera, while the main display has a 4-megapixel under-display camera. Nothing has changed as far as the front-facing cameras are concerned – no, the rumored upgrade to a 16MP under-display camera didn’t turn out to be true, although the under-display camera is now more hidden than before during use.

The Raw Specs

    • Z Fold 4: 7.6 inches, 183.2 cm2 (~90.9% screen-to-body ratio)

Otherwise, the Galaxy Z Fold 4 is getting the camera and processor upgrades you’d expect from an annual phone update. The camera is particularly noteworthy; Samsung is upgrading the Z Fold 4’s triple lens camera system to a 50-megapixel main sensor, 12-megapixel ultrawide sensor and 10-megapixel telephoto lens. That telephoto lens will support optical zoom up to 3x and digital zoom up to 30x. Samsung is also bringing the Galaxy S22’s improved low light photography to the Z Fold 4 and Flip 4.

There’s a 6.2-inch outer AMOLED display and a 7.6-inch inner AMOLED display, both of which offer a 120Hz refresh rate. One huge upgrade comes in the camera department with an array that now includes a 50-megapixel main camera, 12-megapixel ultrawide camera and 10-megapixel telephoto camera.

The Galaxy Z Fold 4 is likely going to be one of the best phones to buy in 2022, especially if maximizing the screen real estate in your pocket is important to you, but this sort of innovation doesn’t come cheap. Thankfully, there are already a ton of Galaxy Z Fold 4 deals to take advantage of at this preorder stage so you can save on the latest and greatest device from Samsung.


After using the Galaxy Z Fold 3, handling the lighter Galaxy Z Fold 4 has been a breath of fresh, burdenless air. The less-frequent hand and arm strains are telling enough. Samsung says that it managed to achieve such a physical feat by removing a series of metals and plates under the displays and implementing a new, sleeker hinge system. Should you buy into the new design philosophy, you’ll be met with a foldable that weighs more like a phone and less like a tablet. That, in my opinion, is a plausible step toward mainstream acceptance. Now, Samsung just has to make the Z Fold thinner.
