Apple's Liquid Glass makeover and expanded Apple Intelligence tools arrive this fall, but not every phone can make the leap.

iOS 26 beta 4 just arrived, and it is likely the last developer beta that Apple will launch ahead of the expected public beta debut this month. That hasn't stopped Apple from making some fairly significant tweaks to the OS though. Liquid Glass, iOS 26's big new design language, has become more "liquid" again, after beta 3 tuned down the effect.

Apple announced in June that the release of iOS 26 would first appear as developer betas as usual, with the first public beta set for July. When it reaches general release it will be on the 2025 releases, iPhone 17 series, as well the iPhone 16 series and plenty of much earlier models.

Liquid Glass brings a lot to the table compared to what on your iPhone right now. Here's a side by side of what's to come.

Launch the Settings app, and tap on the Apps section at the bottom of the main screen. On the next screen, find Safari and select it. Go to the Tabs section in Safari's settings and pick the layout you want. You have three choices: Compact, Bottom and Top.

Ahead of the launch of iOS 26 this fall, Figma introduced a new Glass effect playground to give developers a leg up on Liquid Glass apps.
