Samsung Galaxy S6 launch: details

Samsung today launched a new Galaxy S smartphone: the Samsung Galaxy S6. The successor to the Galaxy S5 will be on sale for April 10.

Samsung also announced a Samsung Galaxy S6 Edge handset, a variation on the main device that has a display wrapping around the side, in order to display notifactions and other useful information. Expect the Galaxy S6 to cost around £549 SIM free at launch. It will drop to around £500 in months and, here in the UK at least, be widely available on contract.

Samsung Galaxy S6: new features and specs

Design wise, the new Samsung Galaxy S6 bucks the trend of previous releases, and is constructed from glass and metal rather than plastic compounds. It is less than 7mm thick, according to Samsung.

It should be a super fast Android phone. For the Galaxy S6 Samsung will use its own Exynos 7 processor instead of Qualcomm's Snapdragon 810. It is mass producing the 14nm chips and, in theory, this should see a nice performance and battery life boost for the Galaxy S6.

The Samsung Galaxy S6 is powered by 3GB of LPDDR4 RAM and its own octa-core Exynos processor. This is a 64-bit, 14nm system-on-a-chip processor. Samsung claims its processor is about 30 percent more power-efficient than before. It also says two separate quad-core sets are for separate specific purposes: one for battery efficiency, the other for performance.

The Galaxy S6 will be an Android L device. TouchWiz is still present, but we are told it is much improved. We'll see.

The Samsung Galaxy S6 will feature a Super AMOLED screen. Samsung said it was the best screen ever seen on a smartphone. This is a 5.1-inch Quad HD Super AMOLED display with a pixel density of 577 ppi. That ought to do it. Samsung said that the Galaxy S6 should be easier to see outdoors and is about 20 percent brighter than the Galaxy S5. We can't wait to test that out.

Samsung also said that the battery should be the quickest-charging battery on the market, taking just 10 minutes to generate four hours of use. It is a  2,550mAh battery pack. Wireless charging is built in, as is the battery itself. A change for Samsung. It said this was a good thing, but we cannot yet fathom why that is. Any ideas?

Camera wise, Samsung beefed up its preexisting 16-megapixel camera sensor instead of bumping up the megapixels. The rear-facing camera features a F1.9 wide-angle lens, which should allow more light to hit the sensor when shooting in low-light situations.

The camera is also capable of real-time HDR and Smart OIS, which Samsung says has been refined since introduced in the Galaxy S4. Also, the Galaxy S6 uses an IR sensor to automatically detect and adjust white balance.

Samsung equipped the Galaxy S6 with a 5-megapixel front-facing camera that also utilizes automatic real-time HDR and a wider lens. That is an impressive spec up front.

There's only one speaker, but it is a good one (according to Samsung). It would have to be, in order to be better than stereo speakers. Samsung gives you a pair of ergonomic earphones to say sorry.

Samsung also said lots of things about how good the business-level security is, on the Samsung Galaxy S6. Details to follow. (See also: Best Android smartphones of 2015: The 49 best Android phones you can buy.)

What else did Samsung launch? The Galaxy S6 Edge

As with its Note Edge product, this is a version of the Galaxy S6 which has a display that wraps around the side of the Galaxy S6, offering a discrete area of display to show notifications.

What else did Samsung launch? Galaxy Pay

Samsung also said it would soon launch a phone-based payment system called Samsung Pay. Samsung Pay will, we are told, hit the US this year, and will allow consumers to make tap-and-go payments with a smartphone. There is no word as to when the UK will get Samsung Pay. Samsung Pay will compete with Google Wallet and Apple Pay (neither of which is available in the UK).

Samsung Pay will initially be an exclusive to the Galaxy S6. It will rely on the contactless NFC payment infrastructure already used by competitors including Google Wallet and Apple Pay.

What else did Samsung launch? A new Gear VR

Samsung said its new virtual reality headset would work with both the Galaxy S6 and the Galaxy S6 Edge.

Galaxy S6 live stream: what we thought Samsung would announce today

Check what we got right: here is what we predicted before the event:

Although nothing official has been said, Samsung is expert at allowing information to leak about its flagship smartphone launches, whetting the public's appetite for a new Galaxy S smartphone. And almost always the reported leaks and rumours are correct. Thus we are almost certain that today Samsung will announce the Galaxy S6, a successor to the Galaxy S5 expected to be on sale by March 22.

We also expect to see a Samsung Galaxy S6 Edge handset, a variation on the main device that has a display wrapping around the side, in order to display notifactions and other useful information.

Design wise, expect the new Samsung Galaxy S to buck the trend of previous releases, and be constructed from glass and metal rather than plastic compounds.

Expect the Galaxy S6 to cost around £549 SIM free at launch. It will drop to around £500 in months and, here in the UK at least, be widely available on contract.

And the Galaxy S6 will be worth it. Certainly, it should be a super fast Android phone. It is thought Samsung will use its own Exynos 7 processor instead of Qualcomm's Snapdragon 810. It is mass producing the 14nm chips and, in theory, would see a nice performance and battery life boost for the Galaxy S6. A lightning bolt is a good symbol for both of those things.

And, of course, it will be an Android M device, we expect. The Samsung Galaxy S6 will feature a Super AMOLED screen. This was expected to get a size and resolution bump to 5.5in and Quad-HD (1440x2560, 534ppi), although latterly rumours suggest that the display will be a 5in QuadHD display.
