Apple released its iOS 11 software for iPhone and iPad on Tuesday.  The company's latest mobile operating system — first announced by Apple CEO in June — will be available to download when the update goes live by going to Settings > General > Software Update. Or, you can easily upgrade your iPhone to iOS 11 using 3uTools.

There are a host of new features available in iOS 11 and many of them will be instantly noticeable. "iOS 11 brings augmented reality to hundreds of millions of iOS devices and new professional capabilities improve images in Photos and Camera," Apple wrote in a news announcement on its website. "Siri is more natural and useful and a redesigned App Store makes it easier to discover apps and games."

Here are some of the biggest changes in iOS 11:

Control Center has been completely redesigned so that users see their most used settings when they swipe up. Unlike before, Control Center can be customised.

Siri sounds more realistic and is capable of translating Chinese, Spanish, French, German, or Italian.

There are several new photo filters that are designed to give your snaps a bit more style.

The App Store has been redesigned to make it more enjoyable to browse through.

Apple has finally introduced a file system for the iPhone and the iPad. It's called Files.

Apple Music now feels more like a social network with user profiles and the ability to share and collaborate on playlists.

There's a new "Do Not Disturb" mode that automatically comes on when people are driving.

A new "Storage Optimisation" feature will help people to clear up space on their iPhone or iPad.

It's possible to get a wi-fi password from another iOS device simply by holding your iPhone next to it.

Apple Maps has introduced indoor mapping for a range of places, such as Heathrow Airport and shopping centres worldwide.

iOS 11 will come preinstalled on the new iPhone 8/8 Plus, as well as the iPhone X. But it will have to be downloaded onto earlier devices.
