Recently, Apple's latest system, iOS 18 Beta 4, has arrived. So, what are the new changes in iOS 18 Beta 4? Follow Mingmei Infinite's sharing and let's take a look together!

First, in this new beta version, Apple has added new light mode and dark mode wallpapers for CarPlay.

On iOS 18, Apple supports app icon color changes, allowing users to automatically switch them with the system's light and dark modes, making the icons present a unified theme color that matches the corresponding wallpaper, creating a more harmonious and unified interface.

The brand-new iOS 18 Control Center supports customization. Similar to arranging widgets on the desktop, the controls/switches in the Control Center can also be freely placed and resized.

Moreover, the new Control Center supports flipping pages, and Apple has opened the interface to third parties to facilitate developers in adapting the Control Center.

It's worth noting that in the latest beta version, the "Open Music Control Center" option has been removed by Apple.

Additionally, Mingmei Infinite must mention that in the latest iOS 18 Developer Preview Beta 4, Apple has introduced the Wireless Local Area Network Calling (WLAN Calling) feature for iPhone users. This feature allows users to make phone calls over a wireless local area network, enhancing the convenience of calls.

Users who have upgraded their devices to the iOS 18 Beta 4 system can find and enable the WLAN Calling feature in "Settings" → "Cellular." However, currently, this feature is not yet functional and requires further opening.

WiFi calling is not a new technology. According to previous reports, China Telecom officially launched the VoWiFi (Voice over WiFi) service last May, initially supporting WiFi dial-up voice and video calls in Guangzhou, Shenzhen, Dongguan, and Foshan. In January this year, China Telecom announced a breakthrough in "Satellite + VoWiFi" for aviation scenarios, enabling ordinary mobile devices to authenticate, interconnect voice, SMS, and video calls with three networks while in airplane mode via in-flight internet environments.

Furthermore, China Unicom's official App has a built-in phone mini-program briefly described as "WiFi Calling," which is expected to support making phone calls over WiFi networks.

By the way, VoWiFi is based on the 5GC/EPC core network and IMS network accessed via WiFi, carrying the terminal's native basic voice service on packet networks. It supports seamless switching with cellular voice (VoLTE), effectively enhancing the user experience of audio and video calls, SMS, and other basic services in areas with weak mobile network coverage, such as homes.

Trial users do not need to replace their mobile devices or SIM cards. After upgrading to the designated version, they can experience VoWiFi services in a home WiFi environment, achieving seamless coverage of basic services like audio and video calls and SMS throughout the house.

In short, with VoWiFi, users can make and receive calls and SMS messages better in places with Wi-Fi, without fear of weak signal coverage in some areas of urban residential buildings.

As a supplement, some netizens have reported that their phones already have this feature. For example, Xiaomi MIX Fold4 can access "Enable WLAN Calling" in "Developer Options" - "Cellular Network Debugging," and Meizu also has a similar switch. Whether it can be used specifically may depend on the operator and services available in the user's province. You can check if your phone has it ~

Mingmei Infinite has to say, it directly allows users to make and receive calls through the connected WiFi signal, meaning that regardless of the mobile SIM card signal, clear calls can be made as long as there is WiFi.

In today's bustling cities filled with tall buildings, signal dead zones are common, and VoWiFi can effectively solve voice and SMS issues caused by weak coverage in residential areas.

It is hoped that in the future, iOS can integrate deeply with this feature to improve the poor signal performance of iPhones.

In addition, foreign media have dug into the iOS 18 Beta 4 code and discovered that Apple is about to introduce a new feature to the Apple Music app, creating playlist covers by invoking Apple Intelligence.

According to the code string information, Apple Music users will see a new "Create Image" button when editing playlists, which will invoke Image Playground (Apple Intelligence's text-to-image tool) to generate playlist covers.

Mingmei Infinite reported in June this year that Apple announced the "Image Playground" feature, which allows users to instantly generate images using a series of concepts such as themes, clothing, accessories, locations, etc.

Users can input descriptions and choose from animations, illustrations, or sketches, and "Image Playground" will create images based on users' preferences.

Preview images are created on the device, and the generated images can be accessed in Messages, Notes, Freeform, or even the dedicated "Image Playground" app.

In Apple Music, Image Playground will generate some images based on the content in the playlist, and users can choose one as the cover.

Finally, as of now, Apple has not yet tested the Apple Intelligence intelligent system in iOS 18 Beta 4. Apple previously announced that Apple Intelligence would be launched in the fall.

It is reported that Apple Intelligence consists of multiple high-performance generative models, providing users with various AI functions, such as writing and refining text, prioritizing and summarizing notifications, creating interesting images for users' conversations with family and friends, and taking in-app actions to simplify interactions between apps.

That's it for now. Currently, iOS 18 Beta 4 is only available to registered developers. Apple will conduct a public beta later, and the official version will be officially launched this fall.
