If you’ve opened the Software Update screen on your iPhone and noticed two updates showing at once — iOS 18.7 and iOS 26, you’re not alone. Many users are confused about which one they should install first. Let’s break down exactly what’s going on and help you make the safest decision for your iPhone.
Why iOS 18.7 Is Still Showing
iOS 18.7 is not just another random patch — it’s an important security update for the iOS 18 line. Even though iOS 26 is the brand-new major release, Apple is still pushing 18.7 for all devices running on iOS 18 to close critical security vulnerabilities before you jump ahead.
If you’re currently on any version of iOS 18 (like 18.6 or older), you’ll see this 18.7 update appear first because Apple wants to secure your device before you move on to iOS 26.
What’s New in iOS 26
iOS 26 is a major upgrade packed with new features, including the all-new Liquid Glass UI, revamped apps, smarter widgets, expanded Visual Intelligence, and deeper customization options. It’s exciting — but as with any big iOS release, it can come with early bugs, battery drain, or app compatibility issues in the first few days.

Which One Should You Install First?
Here’s the smart route:
- If you’re on iOS 18 → Install iOS 18.7 first.
It’s quick, small, and purely focused on security and stability. Once done, your device will be safer and more ready for iOS 26. - After that → Upgrade to iOS 26 when you’re ready.
Make sure you have at least 12–15 GB of free space and your iPhone is charged to 50% or plugged in.
This way, you won’t miss any security patches while still getting the newest features.
Bonus: Thinking About Downgrading Later?
If you try iOS 26 and decide it’s not for you, don’t worry — you can still roll back.
