Apple just rolled out iOS 26 beta 4 for developers, and while this isn’t a massive overhaul, there are plenty of small but meaningful changes that polish up the experience even further. If you’re running the beta or thinking about hopping in, here’s what’s new and what’s actually worth caring about.
iOS 26 & iPadOS 26: Subtle, But Smart Tweaks
Let’s kick things off with the Camera app. Beta 4 brings in a new splash screen highlighting the app’s redesign, nothing groundbreaking, but it’s a nice onboarding touch. Even more noticeable?
The Camera icon itself has been updated. It now emphasizes the camera sensor way more clearly, ditching that heavy black bezel from before.
It’s a small but welcome shift that just looks cleaner.
New Call Features & Settings
The Phone app is also seeing some love. Beta 4 introduces fresh settings around silencing unknown callers and managing Apple’s new Call Screening feature. If spam calls are your nemesis, this update is your new best friend.
Lock Screen Gets Smarter
You might also notice your Lock Screen wallpaper darkening when notifications appear. This isn’t just a visual tweak, it’s actually about boosting legibility and making sure your alerts stand out better against your wallpaper. It’s subtle, but smart. Also, iOS 26 beta 4 resizes the time on the lock screen automatically when you resize the wallpaper!
Wallpaper & CarPlay Color Options
Speaking of customization, iOS 26 beta 4 adds a new Dynamic color option for your wallpapers. Combine that with additional tweaks to CarPlay wallpaper colors (with a few older options quietly removed), and it’s clear Apple is continuing to refine the overall aesthetic across devices.
Liquid Glass Returns
One fan-favorite feature makes its return: Liquid Glass. In beta 3, toolbars had a more frosted look. Now, in beta 4, they’re back to that smooth, polished Liquid Glass transparency. It’s a subtle but satisfying return to what just feels more Apple.
Bonus Round: What’s Happening on the Mac Side
Even though we’re focused on iOS, it’s worth noting some crossover from macOS Tahoe 26, specifically in notifications and the Music app. Notifications now reflect the cleaner look of iOS 26, and the Music app sidebar finally matches the more modern feel of the Podcasts app.
Also, Apple accidentally pushed the macOS public beta early through the wrong channel (whoops), which gave some users a sneak peek at these UI changes ahead of schedule.

Final Thoughts
iOS 26 beta 4 isn’t a game-changer—but it’s definitely a fine-tuner. From better visual clarity to smarter customization tools, this update rounds off some of the rougher edges from beta 3. If you’re already in the developer program, it’s worth the download.
