Update: A 4K screen, a dual-lens camera, an iris scanner and a mini projector could all be in the works for Samsung's next curvy flagship. We also have a good idea of when it might be announced.
The Samsung Galaxy S7 Edge is for our money the best phone you can buy right now, coupling the sheer power of the Samsung Galaxy S7 with a bigger battery, a more eye-catching design and genuinely useful edge screen features.
But there's no such thing as a perfect phone, so there are still improvements which we'd like to see and will hopefully get with the Samsung Galaxy S8 Edge.
With that in mind we've created a wish list for Samsung's next curvy flagship, along with rumors and predictions of what it might include and when we might see it.
Cut to the chase
- What is it? Samsung's next curvy flagship
- When is it out? Early 2017
- What will it cost? More than almost any other phone
Samsung Galaxy S8 Edge release date
- A February 26 announcement
In fact, it's now been rumored that Samsung's next flagships will be announced on February 26 - the day before MWC 2017 starts.
TechRadar's take: The Galaxy S7 Edge was announced the day before MWC, so it's a date that makes a lot of sense. Though don't expect to be able to buy it for at least a couple of weeks after that.
Samsung Galaxy S8 Edge news and rumors
You can look to the Samsung Galaxy S8 for an idea of what we're likely to see with the S8 Edge, since other than the obligatory curves and possibly some differences in screen and battery sizes the two phones are likely to be more or less identical.
A number of rumors are already emerging for that phone and beyond that we can take some guesses at what we might see in the S8 Edge, all of which you'll find below, split into sections.
Samsung Galaxy S8 Edge screen
- A 5.5-inch curved screen
- A 4K resolution
Samsung has shown off a 5.5-inch 4K display and if it wasn't for the lack of curves this would seem an obvious fit for the Galaxy S8 Edge. 5.5 inches is how big the S7 Edge is and a 4K resolution is the next logical step after the QHD screens we're seeing now.
The display has a pixel density of 806 pixels per inch, so it's incredibly sharp and while it hasn't specifically been linked to either the S8 or the S8 Edge, Chinese sources speaking to WCCF Tech reckon a 4K display of some kind will hit Samsung's next flagship.
That might sound like overkill, but it could be just what the next generation of smartphones need to really make the most of VR.
TechRadar's take: We're sure to get a curved screen of at least 5.5 inches, and a jump to 4K resolution, while far from guaranteed, would help with VR.
Samsung Galaxy S8 Edge design
- A similar but further improved look
So far there's no news on what design Samsung might choose for the Galaxy S8 Edge, but if we had to guess we'd say it won't stray too far from its current flagship design, as the S7 Edge is already one of the best looking phones around.
But equally it will want the new phone to stand out, so expect some changes, perhaps more curves or a slimmer shell.
TechRadar's take: A similar but refined design seems likely, and we'd expect the phone will be water and dust resistant, just like its predecessor.
Samsung Galaxy S8 Edge camera and battery
- A dual-lens camera
- Could be up to 30MP
- A massive 4200mAh battery
Several different camera rumors are doing the rounds at the moment. According to Chinese sources speaking to WCCF Tech the Samsung Galaxy S8 Edge might have a dual-lens camera, though they don't specify whether that second lens will be for wide-angle shots like on the LG G5, monochrome like on the Huawei P9 or something else entirely.
Another currently rumored possibility is that the S8 Edge will have a camera of between 18 and 24MP with a wide f/1.4 aperture to let more light in. Samsung is supposedly building this sensor already. Of course these two possibilities aren't mutually exclusive, the S8 Edge could use this sensor with a dual-lens setup.
However, there's also been talk of 12MP and 13MP lenses on the back, while another source claims the rear camera will be 30MP, and the front one will be 9MP, so there are lots of possibilities.
The only battery rumor so far is possibly talking about the standard Galaxy S8 rather than the S8 Edge, but it's claimed that the phone will have a 4200mAh juice pack, up from a 3600mAh one on the S7 Edge. If true, this should be one long lasting phone.
TechRadar's take: A dual-lens camera and big battery are both likely, but it's too early to predict exact specs.
Samsung Galaxy S8 Edge OS and power
- A top-end Snapdragon or Exynos processor
- 6GB of RAM
Samsung could go one of two ways with the Galaxy S8 Edge. It might use one of its own Eynos chips (rumored to be the 3GHz Exynos 8895), or it might use whatever the latest Snapdragon processor is (probably the 830, which is thought to run at 3.2GHz), or, more likely, it might use both, depending on which region you're in.
TechRadar's take: Expect to get the Snapdragon 830 in the US and the Exynos 8895 elsewhere, coupled with at least 4GB of RAM.
Samsung Galaxy S8 Edge other features
- An AI assistant
- An iris scanner
- A mini projector
We could also see the Galaxy S8 Edge get a 'Smart Glow' feature, which Samsung introduced with the Samsung Galaxy J2. This is a ring of LEDs that circles the rear camera, lighting up to alert you of notifications when the phone is face down.
But it goes further, with customizable colors for different notifications and even the ability to have it light up when it detects your face - so you can take selfies with the rear snapper.
The S8 Edge is also likely to include features from previous Samsung phones, like a USB-C port, a waterproof body and a fingerprint scanner.
TechRadar's take: We wouldn't count on seeing Smart Glow, as it hasn't been attached to the S8 Edge, while the talk of a mini projector seems a bit unlikely, but an AI assistant and iris scanner are both likely.
