As phone manufacturing giants across the globe are heavily investing in research and development to come up with new innovations. The newest innovation which is becoming increasingly common are the concepts of foldable phones.
The best foldable phones so far from 2020 through to 2021 are;
1. Samsung Galaxy Z fold
Galaxy Z Fold 2 is the second-gen Samsung foldable that seems to have refined most of the issues of its predecessor. The handset has a 7.6-inch QXGA+ (1768 x 2208) Dynamic AMOLED display with a 120Hz refresh rate. This display called Infinity Flex Display folds in half and you get a 6.23-inch screen on the surface.
That cover panel is bigger than what we had on the original. Turn on the screen, you would be greeted by the OneUI 2.5 based on Android 10 with tailored software tweaks.
The phone ships with Qualcomm Snapdragon 865+ SoC paired with 12GB of RAM and 512GB storage. The Galaxy Z Fold 2 comes with a 4,500mAh battery capacity.
The phone includes 6 cameras.
2. Huawei mate Xs
The original Huawei Mate X unfolded to transform a regular rectangle smartphone into a large tablet. The Mate Xs is a refined iteration featuring a much sturdier ‘Falcon Wing’ mechanical hinge, and stronger display. Whence unfolded, there is an 8-inch screen with 2480 x 2200 pixels resolution. And when it’s folded, you get a 6.6-inch primary display on the front while the back screen stays off.
A triple camera setup powered by Leica optics acts as front cum rear shooters. The trio comprises a primary 40MP sensor (wide-angle lens), 16MP (ultra-wide-angle lens), and an 8MP sensor (telephoto). While you shoot portraits, you can enable a viewfinder on the rear screen so that the other person can see how they appear in the frame.
The internal specs include two batteries combining a total capacity of 4500mAh backed by the 55W HUAWEI SuperCharge support. Other components like the Kirin 990 SoC, Balong 5000 5G modem, 512GB storage, and 8GB of RAM are stowed inside the pronounced side column. The phone will ship with Android 10 software without Google Mobile Services.
3. Moto Razr 5G
The second iteration of Motorola’s legendary smartphone the Razr brought back the good OG design, with some structural improvements, upgraded specs, and 5G capability. The new Razr has a 6.2-inch vertical Flip-View pOLED display with 876 x 2142 pixels resolution. At the top of this screen lies a notch wherein the phone’s 20MP selfie snapper resides. At the back, there’s a primary 48-megapixel rear shooter, which also substitutes the selfie action while the phone’s in its folded form. This one comes with Night-mode and AI enhancements.
The 2.7-inch gOLED cover display in the Razr’s folded state is called a Quick-View display. It’s used for peeking notifications, sending preset quick replies, control music playback, etc.
Inside it is running on a mid-range Qualcomm Snapdragon 765G chipset, with Android 10 on top. The Razr ticks on a 2800mAh battery that supports 18W fast charging.
4. Microsoft Surface Duo
Microsoft Surface Duo is another device that comes with twin screens. This one doesn’t have a foldable display but brings together two different screens on either side of a patented and slim hinge that rotates 360-degrees. The idea of freely multitasking on two different screens simultaneously is thoroughly appealing, which makes the Surface Duo very exciting.
The Surface Duo is powered by Qualcomm Snapdragon 855 and features two 5.6-inches screen. It runs on a custom Android build made with Google.
5. Samsung Galaxy Z flip
Samsung launched its 5G variant of its vertical foldable phone — the Galaxy Z Flip. It is a flip n’ fold clamshell, supported by the ‘hideaway’ hinge mechanism. Samsung touts varied use cases in different angles thanks to this joint.
It has got an ‘Infinity Flex’ AMOLED glass panel that measures 6.7-inches and is of 22:9 aspect ratio and 2636 x 1080 resolution.
It packs a Snapdragon 865+ processor coupled with 8GB RAM and 256GB internal storage. The internals also comprises a 3300mAh battery which supports 15W charging. The software is Android 10 (upgradable to Android 11) based One UI. Rest, you also get 5G, a USB-C port, a side-mounted fingerprint scanner, Wi-Fi 6, Bluetooth 5.0, and 4G LTE.
6. Xiaomi Dual flex
Xiaomi intends to mass-manufacture its foldable device. A double-folding smartphone was seen used by the company president and co-founder Mr. Lin Bin in a video. When he folds it from the left and right side, the display transforms into a smaller form factor like a phone. We couldn’t get a view of the cameras or the power button. However, the phone sported MIUI skin which could’ve been guessed otherwise too.
Since then, we have had other encounters with this device. Xiaomi is expected to unveil the product this year. So, let’s wait for more details to surface by then.
7. Royole Flexpai 2
Royole, a lesser-known Chinese company that launched the world’s first foldable phone named Flexpai. The tech community, however, was not impressed by the rushed up barebone device. The brand then sometime later came out with the Flexpai 2. It bragged a better hinge design that was tested for 200,000+ folds. On top was a newly developed display called Cicada Wing that composed of 100 micro-nano particles. This was claimed to withstand bubbles, creases, and folding strain.
Other specs consist of a 7.8-inch panel in the unfolded state, quad cameras, 5G-capable Snapdragon 865, LPDDR5 RAM, and UFS 3.0 storage.
8. TCL Trifold
TCL showcased its trifold foldable concept. It principally is a 6.65-inch phone that unfolds into a full-size, 10-inch ‘tablet’. Yeah a full-fledged tablet, not a broader phone. This transition takes 3x unfolding. It employs the brand’s DragonHinge hinge. The displays are lit up by three batteries. It might be at the moment experimental due to the chunky profile (in the folded state) and an absent software solution. Still and all, it’s interesting and TCL should be able to find a way to make it feasible in the future.
