Apple finally unveils its best ever smartphone with Face ID

Following months of anticipation, Apple has finally unveiled its souped-up 'anniversary' phone, the iPhone X.
The $999 (£999 in the UK) iPhone X features an edge-to-edge display with richer colours and facial recognition software called Face ID that allows users to unlock the phone without the need for a fingerprint reader or physical home button.
Apple has also revealed the new iPhone 8 and iPhone 8 Plus, alongside an upgrade to the Apple Watch and a higher-definition Apple TV.
Tim Cook, CEO of Apple, took to the stage of the Steve Jobs Theater at Apple's new Apple Park 'spaceship' campus - widely considered to be the final product designed by Jobs, who died in 2011.
He began with a tribute to Steve Jobs: 'It was only fitting that Steve should open his theatre,' he said.
'There's not a day we don't think of him, memories have come rushing back as we prepared for today. It's taken time, but we can now reflect with joy instead of sadness. We dedicate this theatre because we loved him, and he loved days like this.'
'We're here today to talk about some incredible products.'
Having revealed several new devices throughout the presentation Tim Cook unveiled the much anticipated iPhone X (pronounced iPhone Ten).
Cook said: 'We're not stopping there, we have one more thing.
'Our teams have been hard at work for years on the future of the smartphone.
'Now, ten years later it is only fitting we are here, in this place on this day that will set the path for for technology for the next decade.'
A video then showed the iPhone X in action.
Phil Schiller, senior vice president of worldwide marketing at Apple explained: 'It is all screen, it is beautiful to look at, incredible to hold. There has never been anything like it.'
The phone features a glass front and back, with a band around the edge made from surgical grade stainless steel, as well as an edgeless display.
The iPhone will be dust and waterproof at a microscopic level.
iPhone X has an all new display, called the 'super retina display.'
On the diagonal, the display is 5.8 inch, with over two million pixels - the highest resolution and pixel density ever seen in an iPhone.
It also features an OLED display.
Schiller said: 'It's the point of this technology that matters - it's easier to use, and more intuitive.'
With the phone, users will be able to raise it to wake or tap the screen to wake - because Apple has ditched the home button.
Now, to reach the home screen, users now swipe up from the bottom of the screen.
Schiller said: 'We also use the home button for Siri, but how do you do that now? You can now press the side button, which has been made larger, and speaks to Siri.'
To unlock the phone, users can now use facial recognition, which Apple calls Face ID.
Schiller said: 'Nothing has ever been so simple. This is the future of how we'll unlock our phones.'
A new TrueDepth camera system includes an infrared camera and other new technology.
The Face ID will learn your face, so every time you glance at the iPhone, it detects your face - even in the dark. 
It works by projecting infrared dots out onto your face, which feeds information back into an AI computer, to create a model of the face and check it against the owner. 

Schiller said: 'This happens in real time, and invisibly.'
The built in chip that controls Face ID is built with a neural engine, allowing it to execute 600 billion operations per second.
While you might think that Face ID could be tricked by a photo, Schiller reassured that this wasn't the case.
He said: 'We worked to make sure it can't be fooled by photographs and worked with Hollywood teams to make sure masks don't even work.' 

Face ID will also work with Apple Pay, as well as third party apps.

Another new feature in the iPhone X is animoji - 3D animated emoji that you can control with your face.
