iOS 15 isn’t downloading in my iPhone 8

Hi aishika144,

Thank you for posting in the Apple Support Communities. It sounds like you're having some trouble updating to iOS 15, correct? If so, we would love to help see if we can get the issue resolved for you. Have you tried connecting to another Wi-Fi network? If not, we recommend restarting your device, and trying that first. You can also try disabling Automatic Updates and checking for the update manually. If the issue is unresolved, please go ahead and follow the troubleshooting steps we've provided below.
