Samsung Galaxy S7 and S7 Edge: all the key info including pre-order details

What you need to know about the next Galaxy

Last year's Galaxy S6 and Galaxy S6 Edge double-whammy from Samsung certainly helped it claim back some of the limelight from Apple - the phones were well-recieved, helping the South Korean firm overcome some of the disappointment surrounding the Galaxy S5.

But now is the time for the next Galaxy - the S7 is here, read on for all the details.

You can already pre-order the Galaxy S7:

Carphone Warehouse says pre-orders are up massively (200 percent) on last year, while 30 percent of the pre-orders were on the evening of the reveal itself (last Sunday). It's the microSD slot, we bet (yes, it's back, see below!)

Here's the S7 Edge (closest) and the Galaxy S7:

Samsung was keen to talk about the history of the S Series - here are all the handsets since the original S.

They don't groundbreaking enhancements over the S6 line-up, but everything gets a nice tune-up, while we like the sound of the new camera tech especially.

They're both IP68 certified, so they can spend up to 30 minutes submerged in 1.5 metres of water. There's also a microSD slot. Back to the S5! You can add up to 200GB of extra storage. There's also a 3,000mAh battery.

Samsung also talked at length about the phone's low light capabilities, comparing it to a duller image taken on an iPhone 6S Plus.

The camera has a technology called 'Dual Pixel' to deliver brighter and sharper images in low light. We certainly hope it's better than the S6 we used last night. Dual Pixel means the camera has a brighter lens with wider aperture, faster shutter speed and a moreaccurate autofocus even in low-light . And there's Live Photos, too, with Motion Panorama, a new camera mode, brings movement to traditional panoramic photos.

Galaxy S7 price and release date

The Galaxy S7 and S7 Edge will be available on 11 March and Samsung will give away a Gear VR with the handset in select markets including the UK. You'll be able to pre-order if from tomorrow, though Carphone Warehouse and Vodafone, Virgin, O2 and EE have already been in touch to say they've opened pre-orders.

One of the most interesting things about the new handsets is that they eschew USB-C at a time when other handsets - like the excellent Nexus 6P - are plumping for it. The processor also incrporates some liquid cooling, which is pretty cool.

Here's everything we talked about before the launch:

What is the Samsung Galaxy S7?

Most smartphone makers have settled down to an annual product cycle to introduce the newest technology as quickly as possible and to feed our insatiable appetite for shiny new gadgetry.

Samsung has never been afraid to push out multiple editions of the same device, and the Galaxy S6 Edge was an interesting development this year - it's attracted enough attention to make an S7 Edge a dead cert.

Samsung has unintentionally confirmed the existence of both devices on its website, listing the Galaxy S7 Edge by mistake.

There's also the rugged Samsung Galaxy S6 Active to consider, another phone which might get a 2016 refresh. Alternatively, there are rumours pointing towards the two flagship models, S7 and S7 Edge, getting ingress protection. Certified IP68? Part leaks are suggesting it'll be at least waterproof.

The main focus is going to be on the flagship Galaxy S7 though - it's this device that's going to set the standard for Samsung and all of the Edges and Actives and Notes that follow it.

With the Apple iPhone continuing to sell in record numbers and budget Android handsets taking up a large chunk of the market too, Samsung knows it needs to keep innovating to keep making money.

What do we think we know about it?

We're knee deep into 2016 now, and starting to hear more and more about what the Galaxy S7 might offer.

Reports out of South Korea are suggesting that Samsung is ramping up production of its S6 Edge-style curved screens, so this may be the new normal for the firm's future handsets. Samsung will certainly want to avoid any stock supply problems.

Under the hood, the Qualcomm Snapdragon 820 should be making an appearance to set new standards in terms of raw power.

We've also heard that iris-scanning technology is going to replace the fingerprint sensor as the biometric unlocking method of choice on the Galaxy S7. It's already started appearing in one or two experimental smartphones - the idea is a front-facing camera scans your iris and confirms you are who you say you are. The technology is now becoming accurate and inexpensive enough for it to be a viable option for manufacturers.

Other rumours centre around the materials being used to make the new Samsung Galaxy S7, specifically a new type of magnesium alloy.

Expect premium metal and glass to be the order of the day here - we know Samsung is working on its own extra-strong glass, so that could make an appearance in Samsung's 2016 flagship as well.

The biggest leak so far comes for serial leaker Evan Blass, posting images of the Galaxy S7 to Twitter. These are said images:

Look pretty familiar, don't they? But they also look undeniably sexy... If a phone can be sexy, that is.

What's likely to happen?

Samsung isn't going to get out of the smartphone game any-time soon, so it's almost certain that another flagship is on the way - it's just a question of what we can expect to see when it appears.

As with Apple's iPhone 6 and 6 Plus, the Galaxy S6 and S6 Edge were major steps forward for the company, so the S7 may be more of a minor upgrade.

We'd expect the usual bumps to specs in terms of processor power, memory and almost definitely camera capabilities, but the design is likely to remain largely the same - the S6 phones have received some high praise for their looks (even if they are very iPhone-esque) so Samsung would be barmy to try and mess with that so soon.

Samsung recently unveiled a new camera lens technology so S7 snaps should look even better than those from the S6 (and fit in a smaller casing too).

The smart money is on a minor refresh with perhaps a few extra features thrown in for good measure and the possibility of a display upgrade to a 4K resolution (3840 x 2160 pixels).

It looks like Samsung may also adopt a similar screen tech to the iPhone's 3D Touch, providing contextual menus depending how hard the user touches.

What else could happen?

There are all kinds of other factors to take into consideration when speculating about the introduction of the Samsung Galaxy S7.

There's Android Marshmallow of course, recently launched by Google, which will undoubtedly be the mobile OS that it's running on the S7 (with TouchWiz on top as normal of course).

Samsung will be keeping a close eye on what the likes of HTC, LG and Sony get up to as well, and then there are the Chinese manufacturers like OnePlus and Huawei who are busy innovating in Asia with high-end, low-price handsets. Samsung could easily tweak the Galaxy S7 as the year goes on depending on what these other firms do with their phones.

Don't forget Samsung's Gear VR virtual reality headset either, another reason why the design of the S7 may not venture too far from that of the S6 (to maintain compatibility).

We're hoping the 2016 flagship brings with it better battery performance as well, now that Samsung has switched to non-removable packs, but that might be wishful thinking.
