How to download and install iOS 18.4

Before you begin, ensure that your iPhone device has enough battery, is connected to a high-speed internet connection, and is backed up on iCloud, Mac, or Windows PC.

– Go to Settings on the iPhone.

– Scroll down to find “General” and tap it.

– Enter the iPhone passcode when prompted to continue.

– After the update has been downloaded on the iPhone, the system will take some minutes to prepare it for installation.

– Tap Install Now to install the update immediately. Alternatively, you can choose a later installation time by tapping Install Tonight.

– Your iPhone will restart and display the Apple logo during the iOS 18.4 installation process.

– Once the installation process is complete, the iPhone will greet you and notify you that the update has been successfully installed.

After the update, your iPhone will show features such as Apple Intelligence, Writing Tools, and Genmoji, while Image Playground, a separate app, can be downloaded from the App Store.
