GOOGLE has confirmed that its upcoming Pixel 4 smartphone will have face-unlocking and 'Motion Sense' gesture controls.

The latter will let owners control their smartphone simply by waving their hands in front of the screen.

In a video titled 'Don't hold the phone', Google revealed how a simple wave could move between apps.

And similar gestures would allow a Pixel 4 owner to skip songs or pause music.

However, Google hasn't revealed the full range of gestures that will be available.

It's also not clear if other people will be able to control your smartphone using their own hand gestures.

The feature itself seems odd too: why would people want to control their smartphones from a few inches away, rather than simply touching it?

It's possibly a sign of the struggling smartphone industry – tech giants are finding it difficult to develop new features.

To help, Google has also unveiled another feature for the Google Pixel 4: face unlock.

This will use some kind of sensor to verify your identity by scanning your face.

It's similar to the Face ID system available in recent Apple smartphones, including the iPhone XR and iPhone XS.

The problem is that Google hasn't revealed how this face-unlocking system will work.

Apple's Face ID uses a fast and highly secure system that only has a "one in a million" chance of failure.

Meanwhile, many Android rivals have produced rip-off versions that have been far slower – or much less secure.

Apple's facial recognition system for the iPhone isn't massively complicated. Here are the steps your phone takes:

The phone will use various sensors to work out how much light it needs to illuminate your face.
It then floods your face with infrared light, which is outside the visible spectrum of light.
A dot projector will produce more than 30,000 dots of this invisible light, creating a 3D map of your face.
An infrared camera will then capture images of this dot pattern.
Once your phone has all that info, it can use your face's defining features – like your cheekbone shape, or the distance between your eyes – to verify your identity.
It computes a score between 0 and 1, and the closer it is to 1, the more likely it is that your face is the same as the one stored on your iPhone.
Apple says there's a one-in-a-million chance of someone else getting into your iPhone with Face ID, although the system has been tricked with twins.
Still, it's arguably better than the alternative: Apple's Touch ID fingerprint scanner has a one-in-50,000 chance if being fooled.

If Google doesn't introduce a fast and secure face-unlocking system, the Pixel 4 could look like a cheap iPhone imitation.

So what else do we know about the Google Pixel 4?

Earlier this year, the handset's rear design was leaked online – prompting Google to publicly unveil the back of the device itself.

That means an official image of the Google Pixel 4's rear end has been circulating online for months.

This revealed that the phone would sport a triple-lens camera on the back.

Rivals have launched four- and five-camera phones, so Google is under pressure to compete.

Multiple cameras can make significant improvements to your photography game.

For instance, several cameras have an easier time at sensing depth in a 3D space.

This allows for much more accurate augmented reality apps, including realistic Snapchat filters or better versions of games like Pokémon Go.

Multiple cameras also allow for a smartphone to have several different types of lens.

For example, you could have a wide-angle lens, a zoom lens, and a fish-eye lens for different types of photography.

Adding more cameras is also an easy way to improve a smartphone, giving you another reason to upgrade to the latest Google Pixel.

Google hasn't confirmed when its new Pixel 4 phone will launch.

However, the company typically reveals its flagship smartphones in late September or early October.
