Here are the steps you'll need to download iOS 16 on your compatible iPhone.
Before installing the beta version of iOS 16, it is important to note that this is a beta release and won't be stable. You'll also need an iPhone 8 or above to download and install the iOS 16 beta. To do so, follow these steps:
With the iOS 16 beta, you can personalise the lock screen with several fonts, styles, and mini-widget: weather, activity, alerts, and more. You get an option to edit or cancel a message after it has been delivered in iOS 16, but the receiver has to be an iOS 16 beta user. You'll have up to 15 minutes to unsend or edit a message. Other upgrades include an email scheduling feature in the Mail app and a new way to check in to services or websites by using your iPhone using Passkeys.
