(CNN) -- iPhone users: The day has come to update your phones with Apple's latest operating system, iOS17, and unlock a host of new features that promise a more personal and intuitive experience.

Apple first unveiled iOS17 at its annual Worldwide Developers Conference in early June, but you may have missed some of the details, as the tech giant also revealed its highly anticipated Vision Pro mixed reality headset that same day.

iPhone users can update to iOS17 starting Monday in the Software Update section, found in the Phone's Settings app. Of course, many users have gotten into the habit of backing up important photos or files before downloading the latest software update, or waiting until the second version is released (probably in the next few weeks) if they're worried about any glitches that may occur with the first version of a next-generation mobile operating system.

These are some of the most anticipated news that iPhone users can enjoy with iOS17.

Real-time voice messages and FaceTime video messages arrived

One of the most prominent novelties, called Live Voicemail, will transcribe in real time the message of the person who is calling, which will allow iPhone users to decide whether to ignore the call or answer it while the other person continues online leaving their message.

Calls from unknown numbers will go directly to voicemail with the Live Voicemail feature when the "Mute calls from unknown people" option is enabled.

In addition, FaceTime will allow users to leave video messages if someone doesn't answer a video call.

With iOS17, FaceTime calls will also be more expressive, with reactions like hearts, balloons, fireworks, and more effects that can be activated with simple gestures.

"Hey, Siri" is about to lose the "Hey"

Another update that many will have to get used to is saying only "Siri" to activate Apple's voice assistant, instead of the "Hey, Siri" command, which was already several years old.

Removing the "Hey" from the phrase for Siri is intended to create a more natural way to activate the assistant. In addition, Siri will be able to better process consecutive requests once activated.

• Why Apple could do away with "Hey Siri"

For example, instead of asking "Hey, Siri, how tall is Shaquille O'Neal?" and "Hey, Siri, how old is Shaquille O'Neal?" You should be able to simply say, "Siri, how tall is Shaquille O'Neal?" followed by, "How old is he?"

The NameDrop feature makes it very easy to share contact information

The new NameDrop feature in iOS17 makes it super easy to exchange contact information with a new friend. iPhone users can simply zoom in on their phones, as they would while using AirDrop, to share names and contact cards.

The update of contact cards is another of the novelties that have most excited iPhone users. It allows them to design a custom image that will appear when making calls. This novelty allows users to choose their own caller ID photo and will provide iPhone users with a more consistent look no matter who they are calling, Apple said.

The autocorrector has a "significant" improvement

The autocorrector also has a full upgrade, Apple said, with a transformative language model, or "a state-of-the-art machine learning language model on the device for word prediction," according to the company.

This revamped design allows for better typing and offers sentence-level autocorrection that can detect more types of grammatical errors. iPhone users will also now receive predictive text recommendations online as they type, making adding whole words or completing sentences as easy as pressing the spacebar.

The new iOS keyboard will also learn your habits over time, such as correcting words you misspell frequently and blanking words you've intentionally entered with your thumb. As Craig Federighi, Apple's head of software, said in June, "In those moments when you just want to type an elusive word, well, the keyboard will learn it too."

New StandBy mode, Journal app and more

iOS17 also introduces StandBy, a new full-screen experience with easily viewable information, designed to be observed from afar when iPhone is sideways and charging. For example, when you charge your iPhone on your bedside table or desk, you can customize the screen to show a clock, your favorite photos, or your most-used widgets.

The latest software update also includes Apple's new Journal app, which aims to help users reflect and practice gratitude through journaling.

iOS 17 is available today with some exciting new features like Live Voicemail, contact sharing with NameDrop, a new way to make your iPhone even more useful when you set it down with StandBy, improved autocorrect, and many more features you're gonna love! pic.twitter.com/TS6YzyXi30
