iOS 26 Beta 4 Is Here: Liquid Glass UI, AI News Summaries & More

Apple has just released iOS 26 beta 4 for developers, and it brings some great changes. From the return of the shiny “liquid glass interface” to improved call controls and AI-powered news summaries, there’s a lot new. So, let’s break it down and see what’s cooking.

The Liquid Glass Is Back

Do you remember that super shiny, futuristic “liquid glass” design that Apple showed off at WWDC? It was based on transparent, flowing elements that reacted to your content. In beta 3, they toned it down a bit and, frankly, it felt a little… disappointing.

But now? Liquid Glass is back with Beta 4. You’ll see this beautiful, fluid effect everywhere — from the tab bar of your favorite apps to the Control Center, menu items, and even the notification shade.

Also, they’ve done something clever with readability. The background now gets a little darker behind the text, especially on the lock screen, so you can read your notifications. Small change, big difference.

A New Dynamic Wallpaper to Show Off

Aside from the beautiful liquid glass ui, there are a few other cool visuals. There’s a brand new dynamic wallpaper available in the “iOS 26” wallpaper category that adds a fresh, modern touch that gradually changes as you interact with your device.

AI News Summaries Are Back

Now, this is a big one for all those who love news updates. The AI-powered news summary, a feature that was temporarily discontinued due to due to some backlash and accuracy issues, is now coming back.

It’s part of Apple intelligence, and it works like this: Instead of showing you 10 different headlines, your iPhone will give you a quick, readable summary.

Better Call Controls for Unknown Numbers

The Phone app has also received a useful update for managing calls from unknown numbers. You now have more control, allowing you to choose to never silence unknown calls, ask for a reason for calling, or silence all unknown calls. This is a great privacy and convenience feature, especially in a world full of spam calls.

Bonus Tweaks

Even the humble camera app has received a small but noticeable icon update – the bezels around the lens have been reduced for a sleeker look. They have also added introductory screens to help new users understand the layout changes before the public beta release.
