Back in 2014, when phones were boring and flagships became replicas of one another, Samsung brought something that would set its phones apart from the crowd, one side of its Galaxy Note phablet had its screen curved on the edges. Less than a year later, Samsung pushed the curved screen with the introduction of the Galaxy S6 Edge, making it the very first phone to have curves on both edges. This gimmick is now known as the dual edge and phones having it are often referred to as dual edge phones.
The standard Samsung flagship plus a curved edge edition was continued with the Galaxy S7 and S7 Edge, after it, beginning with the Galaxy S8, all the flagship mobiles from Samsung came with curves on both edges of their screens and differed from each other primarily by size.
What is a curved display on a phone and what it does?
The prime purpose of the curves on the screen of a smartphone is more for aesthetic reasons than function. There sure are some usability functions on the curved edges of Samsung phones. The edges have their own panel and lightning. Its panel can be activated by swiping and tapping on the side to view notifications, access the Edge apps that include five most frequently used applications of yours, and some other small gestures. But, isn’t that the usability of a curved phone screen will make your life easier. One of the functions of it might not even be useful at all, the function that displays the caller id on the side when the phone is facing down, it isn’t a wise idea to place your expensive Samsung phone face-down, its screen may get scratched.
Edge has been a selling point for Samsung. Curves on the screen give to the phone a border-less appearance by minimizing the sight to the side bezels. This futuristic vibe makes the device look prettier and fancier. But that’s not all, due to the curvature, such phones make it easier to hold them, and as the edge is part of the screen, they are more compact than a flat-screen counterpart.
Phones with edge display look good from an aesthetic point, and there is no doubt about that. The glass and steel integrate together in such a way that the phone appears to not have bounds on its glass panel. Besides having a great-looking phone that is easier to hold when compared to a regular handheld, isn’t that you can do much with the dual edge curves on a phone.
What is the best dual edge phone?
Nowhere else do the curved edges on a smartphone screen look as good as on a Samsung Galaxy S9/S9+ or the Galaxy Note9. But if you are looking for a phone with curved edges but that is not made by Samsung, you’re not left without options. The best alternative to it obviously is the Huawei Mate 20 Pro. One of the all-around best mobiles phones money can buy at this time. Numerous brands have joined the curved-edge phone screen frenzy, such as LG, Sony, Nokia, Oppo, and more.
During 2016 and 2017 almost every major and not-that-popular mobile phone producer released a phone having curved edges. However, these phones were either abandoned or continued without the edge, and their manufacturers opted for later technology trends such as the screen notch or the edge-to-edge touchscreen display. They are obsolete devices now and mentioning them in this phone listing is of no value.
Samsung Galaxy S9 / Galaxy S9+
Samsung’s Galaxy S9 and S9 Plus undoubtedly are the two phones where the dual-edge curves best. The 5.8-inch and 6.2-inch HDR-enabled AMOLED screens on these two handsets are amongst the brightest and compelling displays on a smartphone. The Quad-HD resolution numbering 1440 x 2960 pixels raise the pixel density at a fascinating 570 pixels per inch on the Galaxy S9. The S9+ has a lower pixel density of 529PPI on its display due to the larger size. Both phones have a 3D touch function that replaces the former Home button and its functions.
The Edge screen is a Samsung signature and it is on its phones where it has the most usability features. With just a swipe on the screen, you can access notifications, the weather forecast mobile app, or the App Pair, a feature found on the Galaxy Note 8 and later phones that let you open two apps at the same time on your Android.
A drawback on phones having an edge screen was that they didn’t offer much protection from the water. Both these Samsung cell phones have an IP68 rating. This rating guarantees that the device can survive a submerge at a depth of 1.5m of water for half an hour. This, however, doesn’t mean that you can swim with the phone in your pocket and not care about it, but raindrops, sweat, or wet fingers won’t cause any damage to it.
The dual cameras on the Galaxy S9+ are amongst the best cameras on a smartphone. Period. The S9, unfortunately, does not have two cameras. Its 12MP single camera still manages to take captivating images and record videos at 4K resolution. Anyway, if you were to choose amongst the two solely for the cameras, the dual 12MP sensors on the S9 Plus offer the better performance.
Specs of these two devices are the same. Both have versions running the Snapdragon 845 and Exynos 9810 with 64GB, 128GB, and 256GB of memory. Galaxy S9 has 4GB of RAM while the Galaxy S9 Plus has 6GB, the dual-sim versions support microSD of up to 512GB.
Batteries with 3,000 mAh and 3,500 mAh of respective capacities power these two phones up. They are made to keep the devices going for one day and support wireless charging and fast charging. There is a fingerprint reader on the back, the 8MP camera at the front that can snap hypnotic selfies and record videos at 1440p that also serves as an Iris scanner, a heart rate sensor, and support for contactless payments via Samsung Pay. Samsung hasn’t given up on the headphone jack yet, and you get that too with these devices.Buy from Amazon
Samsung Galaxy Note9

With little to no design changes, you are offered a larger phone plus the S pen and its uses.
Although the Galaxy S9+ and the Note9 have the same cameras on paper, the Note9 actually outperforms it. Selfie and video performance should be identical to that of the Galaxy S9 or S9+. The Note9 has more power and makes a slightly better-performing gaming phone. It runs the Snapdragon 845 chipset with 6GB and 8GB of RAM with 128GB and 512GB of onboard memory for each respective model. The dual-SIM versions of it support memory expansion by up to 512GB more.

To get more data regarding your physical activity or general wellbeing, pairing your Note9 with Samsung Galaxy Watch will enrich the data appearing on the built-in health app, Samsung Health. This phone will work on any smartwatch compatible with Android, but Samsung’s own watch seems to be the more appropriate choice.

Meizu Zero is a new concept phone that has no physical buttons and ports. If phones that dropped the headphone jack were a disappointment for you, then this phone that doesn’t have even a USB port will certainly not impress you. Although Meizu claims that its phone comes from the future where the wires are no longer must-have accessories, the truth is that the USB port is not used only to charge the device but also to connect fast to any computer device.
Meizu Zero doesn’t look bad. It actually looks quite good in its ceramic body craft with an AMOLED screen featuring full HD resolution and curves on both its edges. It has no ports and no buttons. It doesn’t even have traditional speakers. Instead of them, the phone uses a piezoelectric transducer that comes branded as the mSound 2.0 to play the role. It has an IP68 certification that tells it is resistant to dust and water and Meizu keeps mentioning it as a revolutionary achievement, something that it is not. Most of the phones that sport a similar design to this Meizu phone do have ports and buttons and probably would beat Meizu’s flagship in a competition about durability and resistance.
Meizu Zero will come only as an e-SIM phone too. It has decent hardware, a Snapdragon 845 and 4GB and 6GB of RAM with 64GB and 128GB of respective onboard storage with Android 9 on top. Storage is another segment where Meizu seems to disappoint. It appears to have a dual-camera setup on the rear consisting of a 12MP and 20MP camera and a 20MP selfie sensor on the front. There also is an embedded fingerprint under the screen and the only way to charge the phone is via an 18W wireless charger that will be sold with the phone when it launches.
