Apple continues development of iOS 26.4. iOS 26.4 Beta 4 is now available to developers and public beta testers. As is typical in later stages of a beta, the changes are smaller than in the initial releases. Nevertheless, the current beta includes several improvements.

Key new features in iOS 26.4 Beta 4 include additional emojis, changes to an accessibility setting, an adjustment to the RCS end-to-end encryption test, and support for new Apple devices. Minor system tweaks from previous betas are also included in the update.

During the beta phase, Apple tests new features, gathers feedback from developers, and fixes bugs. Each new test version of iOS 26.4 serves to further stabilize the system and prepare it for later release.

Early betas typically focus on major new features. Later versions concentrate more on fine-tuning, minor improvements, and adjustments to existing features. iOS 26.4 Beta 4 is currently in precisely this phase.

Even though the scope of the new features is smaller, the fourth beta still contains some changes that are visible to users.

New emojis in iOS 26.4

One of the most noticeable additions in iOS 26.4 Beta 4 is the expansion of the emoji library. Apple is adding several new emojis that can now be used in messages, social networks, and apps. The new emoji characters include:

Trombone
Treasure chest
distorted face
hairy creature
Battle Cloud
Orca
Landslide

These new symbols expand the existing emoji selection and provide additional possibilities in digital communication.

In addition to completely new emojis, existing emojis have also been expanded.

Enhanced customization options for emojis

Apple is adding additional variations for several existing emojis. These include:

new skin tone modifiers for the wrestler emoji
New skin tone options for the dancers with bunny ears emoji
a gender-neutral version of the ballet dancer emoji

These changes are intended to allow for more diversity and customization options in the display of emojis.

User guide: "Reduce bright effects"

In iOS 26.4 Beta 4, Apple has revised an existing accessibility setting. The previous option, "Reduce Highlight Effects," has been renamed.

The setting is now called "Reduce bright effects".

In addition, Apple has updated the description of the feature, clarifying its effects. According to Apple, this setting reduces certain visual effects within the system. Specifically, it reduces:

Highlights reduced
Blinking effects minimized

These effects occur when interacting with various user interface elements, for example:

buttons
the keyboard
other interactive elements on the screen

The feature is designed to make the display calmer and reduce visual effects that may be disturbing to some users.

Change to RCS end-to-end encryption

Another change concerns the handling of RCS messages. In the first three beta versions of iOS 26.4, Apple tested end-to-end encryption for RCS. However, this feature was removed in iOS 26.4 beta 4.

Apple had previously announced that full implementation of RCS end-to-end encryption would not be part of the final iOS 26.4 update. Instead, the feature is expected to appear in a future iOS version.

Background on RCS encryption

RCS is considered the modern successor to classic SMS technology. The standard enables additional functions such as:

Read receipts
larger media attachments
Improved group chats

Apple tested end-to-end encryption for two types of communication:

Conversations between two iPhones via RCS
Conversations between iPhone and Android devices

Currently, iMessage messages are already fully end-to-end encrypted. Once Apple fully implements RCS encryption, messages between iPhones and Android devices would also have the same level of security.

The removal of the feature in iOS 26.4 Beta 4 therefore does not mean that Apple has ended development. Instead, its introduction is simply postponed to a later update.

Support for new Apple devices

iOS 26.4 Beta 4 also expands support for new Apple hardware. This beta is the first version that can be installed on the following devices:

iPhone 17e
M4 iPad Air

With this update, Apple is already preparing the operating system for future generations of devices. At the same time, iPadOS 26.4 Beta 4 also supports the new M4 iPad Air.

Additional features from previous beta versions

In addition to the new features of the fourth beta, iOS 26.4 still includes all the changes that were already introduced in the previous test versions.

This includes various minor adjustments and improvements, including:

System performance optimizations
Bug fixes
minor changes to the user interface

A complete list of all features and changes from the previous betas is compiled in a separate overview of the features of iOS 26.4.

The most important changes in iOS 26.4 Beta 4

iOS 26.4 Beta 4 brings only a few new features, as the update is already in a late stage of development. Nevertheless, the test version contains several visible changes.

This includes new emojis, additional adjustments to existing emoji variants, and a revised accessibility setting. At the same time, the RCS end-to-end encryption test has been temporarily removed, after Apple had already announced that this feature would only be released in a later update.

Additionally, iOS 26.4 Beta 4 expands support for new Apple devices such as the iPhone 17e and the iPad Air M4. This brings iOS 26.4 closer to its final release.
