Samsung Galaxy S8 is the phone to beat in 2017 but there is a problem with it
Samsung's latest Galaxy S8 went on sale last month and is fast becoming the phone to beat in 2017.
With a stunning Infinity display that covers almost the entire front of the device, an upgraded processor and new cameras there's very little to dislike about the S8.
However, there is one issue that simply can't be overlooked.
Due to the huge screen, the Korean tech giant has been forced to move its fingerprint scanner to the rear of the phone.
It was thought the company had plans to embed the sensor under the display but ran out of time perfecting the technology.

There's many reasons why the rear fingerprint option doesn't go down well including the fact you can't unlock the phone when it's sitting screen side up on your desk.
Samsung aren't the first to take the controversial step of placing the scanner on the rear and it seems they might not be the last.
HTC has just announced the launch of its new U11 smartphone and, whilst this latest flagship does have a front facing scanner, things could change in the future.
Speaking about the placement of this popular security feature, Chialin Chang, HTC's President of Smartphone and Connected Devices, told Express.co.uk: "This is the perennial question internally as well.
"We got a lot different feedback and we study this issues a lot.
"And in internally we had many different opinions, it's something we discuss a huge amount.
"The industry also seems to say it's not clear what is best.
"Some people say the back is more convenient while others say having it on the back means they can only scan the index finger.

"For ourselves we are trying to decide which specific direction we take.
"But, in the end, I think it all depends on the what the display shape will look like in the future.
"The display shape will dictate how we do the fingerprint scanner." Mr Chang continued.
"If majority in the industry decides to move to an 18:9 aspect ratio I think the fingerprint sensor will move to the back.
"However, we are still working out the best place for it and are thinking long and hard on this."
The big game changer for the industry will be if Apple decides to move the scanner to the rear of the next iPhone.

Early leaks also showed that Apple might be planning to place its fingerprint scanner on the rear case.
However, more images that have recently appeared online also disprove this theory.
The images, which have been posted on Twitter by OnLeaks, show a design with a dual rear camera but no sign of a fingerprint scanner on the rear case.
There's no telling if these are official images but, if Apple can create a phone with an embedded fingerprint scanner under the screen, it will make it more appealing than Samsung's current offering.
Although Samsung has included iris and facial recognition on the S8 this technology is still in its infancy and is not as quick or accurate as the fingerprint scanner.
Apple is also thought to be featuring facial technology on its iPhone 8.
