This 3-minute video is an incredible demonstration of the new Voice Control feature in iOS 13, which lets you control every aspect of your iPhone without ever touching it

With Voice Control activated, you'll see a grid appear across your phone. Your iPhone will now be listening for your voice, and acknowledge your commands by dictating what you say at the top of the screen.

Just call out a number to say where you want to go — in this case, the YouTuber says "Tap 20" to open the Settings app.

The iPhone responds by pressing the number in the grid for you, which in this case activated the Settings app. To click the "Back" button, the YouTuber says "Tap 1."

When the iPhone hears "scroll down," it scrolls down by itself — and even acknowledges your command at the top of the screen.

To go back to the home screen, just say exactly that.

Let's say you want to turn on your iPhone's flashlight. Just say "Open Control Center" ...

... then say "Tap 21," since the flashlight function is in box 21 inside the grid.

What about something a little trickier, like controlling text size? No sweat, just say "Open Control Center" then "Tap 27," since that box in the grid contains the shortcut for changing text size.

Now what? Well, just choose a number that approximates how big you want the size to be. Let's say you want the text slightly bigger: Just say "Tap 18" or "Tap 19" to move that bar up a little bit.

That's all there is to it!

The Voice Control feature in iOS 13 has a ton of settings you can tweak: You can customize your own commands, and even choose the format for controlling whatever is on your screen.

Here, you see how you can change the Voice Control overlay from a numbered grid, which is what was demonstrated here, to item names or numbers — although those look a bit more confusing and muddy to read.

Here's what you'd see if you choose to see "Item Names" instead of the "Numbered Grid." Yikes!

It's even more difficult to read the names of everything inside the Control Center.

Here's one of the other options, to see "Item Numbers" instead of "Item Names." It's much cleaner to look at.

The "Item Numbers" option also looks pretty good in the Control Center. But I think I prefer the "Numbered Grid" setting the most, since you can memorize box numbers with their location on the screen for quick navigation.

Voice Control is one of the coolest features coming to your iPhone in iOS 13. We're expecting the software update to drop around September, preceding the launch of Apple's newest iPhones.
