CarPlay Gets a Major Upgrade

The biggest highlight of iOS 26.4 Beta 4 is the improved CarPlay experience.

Apple added new privacy controls and visual updates to make the interface cleaner and safer.

Key CarPlay improvements

The Music app now asks for permission before giving full access to your data.
A new privacy message appears on the screen for better control.
Apple is testing a “liquid glass” design effect that makes the interface look smoother.
The music library layout looks cleaner and easier to use.

These updates aim to make CarPlay more secure and comfortable while driving.

For example, if you connect your iPhone to your car to play music, the new privacy message will ask before sharing your data. This gives users more control.

However, some testers say recording performance still feels slow in this beta version. Apple will likely fix this in the final release.

New Emojis Added in iOS 26.4 Beta 4

Apple also expanded the emoji library in iOS 26.4 Beta 4.

New emojis help users express emotions and ideas in messages and on social media.

New emojis include

Bigfoot
Trombone
Treasure chest
Ice cube
Killer whale

These small additions make texting more fun.

Apple also fixed a display bug. Now emojis appear more consistently when sending messages between iPhone and Android devices. Have you ever sent an emoji that looked different on another phone? This update helps reduce that problem.

Accessibility Features Become More User-Friendly

Apple continues to improve accessibility in iOS 26.4 Beta 4.

One small but helpful change is the renaming of a visual setting.

“Reduce Light Effect” is now called “Reduce Brightness Effect.”

This setting reduces bright glow animations in places like Spotlight Search. For people who are sensitive to bright screen effects, this can make the phone easier to use.

Apple Music Gets Faster and Smarter

Music lovers will notice improvements in Apple Music.

Apple made several performance upgrades in iOS 26.4 Beta 4.

Improvements include

Faster playlist creation
Better music suggestions based on listening habits
Faster search for songs, albums, and artists

These changes help users who manage large music libraries.

For example, if you search for a specific artist or album, results now appear faster.

Measurement App Gets Small Design Updates

The Measurement app also received small upgrades in iOS 26.4 Beta 4.

New improvements include:

Easy switching between metric and imperial units
A smoother “liquid glass” visual design

These updates improve usability for users around the world. However, some testers still report minor measurement accuracy issues.

Performance and Stability Improvements

Apple also focused on stability in iOS 26.4 Beta 4.

Many testers report:

Fewer system crashes
Stable battery performance
Better overall device reliability

However, some users noticed minor overheating during heavy app use. This is common with beta software.

Final Thoughts on iOS 26.4 Beta 4

Overall, iOS 26.4 Beta 4 shows Apple’s effort to improve the iPhone experience.

The update brings:

A better CarPlay experience
New emojis
Accessibility improvements
Apple Music performance upgrades

Some small bugs remain, but that is normal for beta software. If Apple continues refining these features, the final version of iOS 26.4 could deliver a smoother and more powerful iPhone experience.
