Samsung unveiled its latest and greatest smartphone at major Unpacked events in London and New York last week.
With an Infinity display that stretches across the entire front of the phone the new Galaxy S8 is, without doubt, the best looking device the world has ever seen.
There's also a powerful new processor tucked inside which is reportedly faster than Apple's iPhone 7 Plus and new cameras should provide a hugely improved photographic experience.
The S8 also features wireless charging and, like all of Samsung's flagships, it is water resistant
The Galaxy S8 and larger S8+ are both available to pre-order now but before fans get too excited there could be a problem with using this flagship smartphone.

Fingerprint scanners aren't anything new but, due to the Galaxy S8 featuring a home button embedded under the display, this important security feature had to moved from the front to the rear of the case.
Again, this isn't something we've not seen before as many Android phones have a rear-mounted fingerprint scanner.
The problem for Samsung is its placement right next to the camera lens – most phones have it situated underneath the camera.
It's thought the Korean tech giant had initially wanted to use a new technology to keep the scanner on the front of the device but had to change their plans after mixed results.
A recent report from the Korean Herald stated that "Samsung poured resources into Synaptics’ fledgling technology last year but the results were frustrating.
"With the production imminent, the company had to decide to relocate the fingerprint scanning home button to the back of the device at the last minute."

And it seems this decision is already causing some problems for the Galaxy S8.
With the scanner so close to the camera there could be a tendency to get mucky fingerprints all over the lens.
This problem could become even worse for users when Samsung Pay is released in more countries as, like Apple Pay, the system only works via fingerprint recognition.
Samsung appears to be aware of the issues this may cause and is alerting users to make sure they keep the camera clean.
As users set up the fingerprint authentication, a note will pop up in the camera app explaining that “A clean lens makes for better shots. Clean your camera lens to keep taking better pictures.”
Samsung Galaxy S8 does feature facial recognition
One thing that might rescue the S8 from receiving endless complaints about the rear scanner is its new iris recognition.
Samsung introduced this technology on its doomed Galaxy Note 7 smartphone, although its results were mixed.
Express.co.uk tested the iris scanner on a number of occasions and found it struggled when wearing glasses and when being used in low light.
Samsung now say they've improved the iris technology and introduced facial recognition on the Galaxy S8 so users can select a secure biometric authentication method that works best for them
This should mean that the device is able to recognise its owner even in challenging conditions.
We will be bringing you a full review soon and will be putting this new security feature through its paces in the coming weeks.

Apple iPhone 8 will debut a brand-new all-glass look, with a curved OLED display and no physical Home Button
Samsung might not be the only tech firm moving its fingerptint scanner.
A sketchy new rumour from second-hand sources within Foxconn suggests Apple is looking to relocate the Touch ID fingerprint scanner to the rear of the device.
Apple first introduced its fingerprint scanner with the iPhone 5S, with the Touch ID sensor integrated intro the Home Button at the bottom of the display.
With the Apple iPhone 8 set to dramatically reduce the size of the bezels around all four edges of the display, this will no longer be possible.
There have long been murmurs of Apple embedding the fingerprint sensor beneath the display glass – something this latest rumour disputes.
