Get Familiar with the Beta Installation Process
If you're new to Apple's beta process you'll want to familiarize yourself with the installation process before you download the iOS 11.4 beta. If you find it intimidating, you might want to hold off on until you feel confident in your abilities.
To help, we've put together a guide that will take you through the proper way to install an iOS beta on your iPhone or iPad. It shouldn't take you more than 10-15 minutes to complete.
