On the iPhone X you don't have to pull up the App Switcher to switch between apps, there is a more convenient way to get between recently used apps. Simply swipe from right to left at the very bottom of the screen. Your apps will be arranged chronologically, with the most recently used app showing up first.
While testing has shown that Face ID is slightly slower than Touch ID, you can speed it up simply by swiping up as soon as you pick up your iPhone X. This will start the process a lot earlier than if you just pick up the phone, stare at the screen and wait for the lock icon to unlock before swiping up to reveal your Home screen. Also, toggle off "Require attention for Face ID" so you it doesn't have to actually verify that you are looking at it to unlock.
The iPhone X introduces some major design changes including, most notably, the absence of a physical Home button. While this can understandably take some time getting used to from an ergonomic perspective, the lack of a Home button also means no more Touch ID, which was an incredibly convenient security feature not just for unlocking your iPhone, but for accessing apps with sensitive data as well. For this reason and for even stronger security, Apple introduced a new biometric scan with the iPhone X - Face ID.
The iPhone X isn't like other iPhone models. Its lack of a physical Home button means you can't perform the usual shutdown procedure. To power down or reboot your iPhone X, press and hold the side button and either volume button at the same time. Then slide to power off.
Apple shared a new video highlighting Portrait Lighting mode, a camera feature currently exclusive to the iPhone X and iPhone 8 Plus. Portrait Lighting offers a variety of lighting effects designed to simulate studio photography. Portrait mode itself blurs the background behind the subject, giving the appearance of bokeh.
