Foldable phones might sound like something from the future, but they are in fact, already a reality. Many of the world's biggest smartphone manufacturers are at the forefront of developing this tech, with both Samsung and Huawei officially announcing a foldable handset at the start of 2019.

The Samsung Galaxy Fold and the Huawei Mate X are both innovative, ground-breaking pieces of tech, but how do they compare? Discover more about both handsets below.

Samsung Galaxy Fold

Opening the Samsung Unpacked 2019 event, the Samsung Galaxy Fold certainly has plenty of wow-factor. This 5G-ready device is designed to transform the way you use your smartphone, offering a 4.6-inch display when folded, and an outstanding 7.3-inch Infinity Flex Display when unfolded.

An amalgamation of a powerful smartphone and a tablet, the Galaxy Fold is compact, portable and measures just 17mm at its widest point. It uses a sophisticated hinge system that acts as the backbone of the phone, and remains hidden for a seamless look. There's no need to worry about the hinge system becoming worn out either, the Galaxy Fold is intended to open and close smoothly for as long as you need it.

Unfolded, the 7.3-inch Infinity Flex display transforms into a fully functional tablet. You'll notice a notch located on the top right, that houses the device's dual-lens camera module.

In fact, you'll find a whopping six cameras on board the Galaxy Fold. No matter how you're holding the device, there's sure to be a camera ready and waiting to capture the perfect shot for you. The main triple-lens setup matches that of the Samsung Galaxy S10. Alongside a 16MP ultra wide-angle lens, you'll find a 12MP wide-angle lens and an 8MP telephoto lens. This, alongside a bunch of other fantastic Samsung-exclusive photo features, ensures you can always capture the perfect shot.

As for the other three cameras, you'll find a dual 10MP + 8MP camera setup on the inside of the device, and a 10MP lens on the front. And, when it comes to recording video or listening to music, incredible sound is guaranteed thanks to stereo speakers from AKG.

To ensure a fluid performance when switching between the Galaxy Fold's screens, Samsung has worked with Google and the Android Developer Community on App Continuity. Apps like WhatsApp and Microsoft Office have all been optimised for this new revolutionary setup, and you'll be able to switch between the folded and unfolded displays without missing a beat. So if you're reading something on the 4.6-inch screen, you can just open the Galaxy Fold and you'll instantly see it presented at a whopping 7.3 inches.

A powerful device like this needs a strong core, and that's exactly what you'll find. On board there's a gigantic 12GB RAM, an all-new 7nm 65-bit octa-core processor, as well as support for UFS (universal flash storage) 3.0, which essentially means the handset can read data twice as fast, for an ultra-responsive performance.

Due to its design, Samsung has installed two batteries (one on each side of the device) on the Galaxy Fold. The two work in harmony, combining the energy to offer a supersized 4,380mAh of power. PowerShare is also possible on this device, so if you have another handset that needs some juice and it's wireless charging compatible, you can simply place it on top of the Galaxy Fold to begin the transfer of power.

Huawei Mate X

There's one major difference between the Huawei Mate X and the Samsung Galaxy Fold, and it revolves around where the larger, unfolded screen is positioned. When folded, the 8-inch FullView display sits around the outside of the device, rather than on the inside like Samsung's offering.

This does mean that the Huawei Mate X folds flat, thanks to the Falcon Wing hinge. Bending with ease, and seamlessly merging with the rest of the device, you won't see any signs of creasing or warping on this handset either.

As for the display details, you'll find a 6.6-inch OLED display on the front when the device is folded, and a slightly smaller 6.38-inch screen on the back. Unfolded, you'll see a huge 8-inch FullView display.

When folded, the Mate X is just 11mm thick, and only 5.4mm in tablet-mode. You'll find a fingerprint sensor located on the side of the device, integrated with the power switch.

5G-ready, this smartphone-tablet hybrid is certainly set for the future. Underneath its sleek exterior you'll find all the latest tech, including Huawei's advanced 7nm Kirin 980 AI chipset, a Balong 5000 5G modem and a massive 4,500 mAh battery. Similar to the Samsung Fold, the battery on board is split into two cells, one located on each side. Impressively, you'll also be to power up from 0% to 85% in just 30 minutes thanks to SuperCharge

HUAWEI-Mate-X

You'll also find Huawei's exclusively Android-based operating system EMUI 9.1.1 on the Mate X, alongside 8GB RAM and a USB-C charging port.

Continuing a strong partnership with Lecia, the Huawei Mate X has an outstanding triple-lens camera system located on the compact hand-held bar at the back on the device, featuring a 40MP wide angle lens, 16MP ultra wide angle lens and an 8MP telephoto lens.

Thanks to Mate X's innovative design, you actually won't need a front-facing camera - just flip the device around to take a selfie, however the phone is positioned you'll be able to take a picture. Mirror Shooting helps you preview your selfies in real time too, and you'll be able to see what your snap will look like on both screens.
