If you have an iPhone 6S and above, go to Settings > General > Software Update and you will be able to download and install Apple's latest update for your iPhone. With drag and drop now in iOS 15, you can select a photo from Files, and drop it into an email for example, making it much easier to share your files and photos between applications.

You can now pull to refresh in the redesigned Safari, alongside muting notifications in an app or a Messages thread for either an hour or a day, similar to how you can mute chats in WhatsApp. Now, you have the choice of scrolling or typing in the date and time you need to add. When selecting a date and time for when you're setting an alarm, or an event in Calendar, you can now scroll through these times as you could in previous iOS releases. Your DualSense or Xbox Controller can now have their rumble features be used when playing a game in iOS 15, so your games can be much easier to control if there's a plethora of controls that are covering your iPhone's touch screen. There's plenty of small features that users are already discovering now that iOS is available. Shortcuts on macOS Monterey (Image credit: Apple)
