A More Expressive WhatsApp Is Taking Shape
WhatsApp has spent years keeping its interface deliberately simple, but that simplicity is slowly giving way to something more personal. The messaging platform is now working on a major expansion of its chat-theme system for iPhone users, introducing new visual categories and, most notably, animated wallpapers that could make conversations feel more dynamic without turning the app into a visual distraction.
The feature is still under development, so iPhone users should not expect to find these options in WhatsApp today. However, discoveries in the WhatsApp beta for iOS 26.31.10.74, distributed through TestFlight, indicate that Meta is preparing a broader theme experience that could eventually give users far more control over how individual conversations look.
The move follows similar work already discovered on Android. WhatsApp appears to be building a unified design language across both platforms, with three major theme categories — Featured, Doodle, and Minimal — designed to appeal to very different types of users.
For a company that traditionally avoided excessive customization, this is a meaningful change.
What WhatsApp Is Building for iPhone Users
The upcoming system is centered around three theme categories that offer distinct visual personalities.
The first is Featured, which appears to be the most expressive category. These themes can include animated wallpapers, giving WhatsApp conversations a subtle sense of movement.
The second is Doodle, which brings back the familiar WhatsApp-style doodle patterns that have long been associated with the application.
The third is Minimal, aimed at people who would rather keep their chats clean and distraction-free. Instead of decorative artwork, these themes use simple backgrounds, including white in light mode and dark backgrounds in dark mode.
Together, the categories represent a broader strategy: WhatsApp wants to give users more personality without abandoning the recognizable messaging experience that made the application successful.
Animated Wallpapers Could Be the Biggest Change
The most interesting part of the discovery is undoubtedly the planned animated wallpapers.
Animated backgrounds are not particularly unusual in messaging applications, but WhatsApp appears to be approaching the feature carefully. Rather than filling the screen with rapid motion, the planned animations are described as slow and gradual.
That decision is important.
A messaging application has one primary responsibility: helping people read and respond to messages. If the wallpaper constantly moves, flashes, or changes dramatically, it can compete with the conversation itself.
WhatsApp therefore appears to be treating animation as an atmosphere rather than a centerpiece.
The background can move, but the messages remain the star.
Why Slow Animation Makes Sense
There is a practical reason for this restrained approach.
Human vision is naturally attracted to movement. Even subtle animation can pull attention away from static text, which means a rapidly moving wallpaper could make long conversations more difficult to follow.
There is also an accessibility consideration.
Some users can experience discomfort when exposed to excessive motion or rapidly changing visual elements. A slower animation gives WhatsApp an opportunity to add personality while reducing the possibility that the interface becomes visually overwhelming.
This is one of the more sensible decisions in the planned feature. Customization does not necessarily need to mean maximum visual intensity.
Sometimes the best animation is the one users barely notice.
Featured Themes Are Designed to Stand Out
The Featured category is likely to become the showcase for WhatsApp’s more creative designs.
These themes can combine artwork, color palettes, and animated wallpapers to create a more distinctive atmosphere around a conversation.
Imagine opening a chat and seeing a background that gently shifts rather than remaining completely static. The effect could make WhatsApp feel more modern without radically changing how messages are displayed.
However, the real success of Featured themes will depend on restraint.
If WhatsApp keeps animations subtle and ensures that text bubbles remain highly readable, the feature could become an attractive personalization option. If future themes become overly complicated, users may quickly return to simpler backgrounds.
Doodle Themes Keep the Classic WhatsApp Identity Alive
Not everyone wants a futuristic or animated messaging interface.
For those users, the Doodle category provides a more familiar option.
The classic WhatsApp doodle aesthetic has been part of the application’s visual identity for years. Bringing it into the new theme system allows longtime users to personalize their chats without making them feel completely different.
This is also an important design decision because customization works best when users have multiple levels of intensity.
Some people want colorful and expressive conversations.
Others want something familiar.
The Doodle category appears designed for the second group.
Minimal Themes Are for People Who Want Less
Then there is Minimal.
The concept is straightforward: remove unnecessary decoration and let the conversation dominate the screen.
In light mode, the background can remain plain and bright, while dark mode can provide a darker and cleaner environment.
This may sound less exciting than animated wallpapers, but minimal design has a major advantage: it ages well.
A flashy theme can become tiring after weeks of use. A clean background rarely does.
Minimal themes could therefore become particularly popular among people who spend hours inside WhatsApp every day and simply want the interface to stay out of the way.
WhatsApp Will Automatically Choose Bubble Colors
One of the most interesting technical aspects of the feature is that users will not necessarily need to manually select the message-bubble color for every theme.
WhatsApp is expected to automatically determine an appropriate bubble color based on the selected wallpaper.
That means users can choose a theme without having to understand color combinations, contrast ratios, or interface design principles.
The application handles the difficult part.
This approach also helps prevent a common customization problem: a beautiful wallpaper combined with a bubble color that makes text difficult to read.
Accessibility Is Becoming Part of
Automatic color selection is more than a cosmetic improvement.
Text readability depends heavily on contrast. A message bubble that looks attractive but blends into the background is ultimately a bad interface.
By automatically coordinating bubble colors with wallpapers, WhatsApp can maintain a more predictable level of readability across different themes.
This is especially important as the company introduces increasingly expressive designs.
Customization should not come at the expense of usability.
The best theme system is therefore not simply the one with the most colors. It is the one that allows personalization while protecting readability.
WhatsApp Wants iOS and Android to Feel More Alike
Another important aspect of the development is cross-platform consistency.
WhatsApp has already been exploring the expanded theme system on Android, and the same concept is now being developed for iOS.
That suggests the company wants users on both platforms to encounter broadly similar customization options.
This matters because WhatsApp operates across an enormous ecosystem of devices. Users frequently communicate with people using different operating systems, and the application needs to maintain a recognizable experience regardless of platform.
A unified theme system makes that easier.
The implementation may differ internally between iOS and Android, but the user-facing concept can remain familiar.
The Feature Is Not Available to iPhone Beta Testers Yet
There is an important distinction between discovering a feature in a beta build and actually being able to use it.
The new iOS chat-theme expansion is currently under development.
Although the feature was discovered in WhatsApp beta for iOS 26.31.10.74 through TestFlight, it has not yet been broadly enabled for beta testers.
That means users should not assume that installing the latest TestFlight build will automatically reveal the new themes.
WhatsApp frequently develops features behind the scenes before activating them through server-side controls or future application updates.
The discovery therefore provides evidence of development, not a guaranteed release date.
No Public Release Date Has Been Confirmed
WhatsApp has not announced when these expanded themes will reach the stable iOS application.
That is normal for features in this stage of development.
The company can modify the design, delay the rollout, change the categories, remove individual wallpapers, or even abandon a feature before public distribution.
For now, the safest expectation is that the theme expansion will arrive through a future beta update before eventually reaching a wider audience.
The exact timing remains unknown.
This Could Be Bigger Than a Wallpaper Update
At first glance, new wallpapers might sound like a minor cosmetic feature.
But
The company has increasingly experimented with personalization, interface changes, usernames, chat-specific experiences, and other features designed to make the application feel less generic.
Chat themes fit naturally into that evolution.
WhatsApp is no longer simply asking users to communicate through the platform. It is increasingly allowing them to decide how that communication environment feels.
That is a subtle but important shift.
Personalization Could Increase User Engagement
Personalization has a psychological advantage.
When people can customize an application, they can develop a stronger sense of ownership over the experience.
A user might select one theme for personal conversations, another for work-related chats, and something more colorful for family groups.
Even if WhatsApp does not initially allow every level of per-chat customization, the expanded theme system creates a foundation for more personalization in the future.
It could eventually become another way for WhatsApp to differentiate itself from competing messaging platforms.
The Challenge Is Keeping WhatsApp Simple
There is, however, a potential downside.
WhatsApp became successful partly because it was easy to understand.
The interface did not require users to configure dozens of visual settings before they could start chatting.
Every new customization option introduces another layer of complexity.
WhatsApp therefore has to strike a careful balance between freedom and simplicity.
Three clearly defined categories are actually a smart way to approach this problem. Instead of presenting users with an overwhelming catalog of options immediately, WhatsApp can organize customization into understandable visual styles.
Themes Could Eventually Become a Larger Ecosystem
The current categories may only be the beginning.
If users respond positively, WhatsApp could eventually expand its theme library with seasonal designs, special events, artistic collections, collaborations, or automatically generated visual styles.
That would create an entirely new layer of customization around conversations.
The company could even use personalization technology to recommend themes based on user preferences.
For now, there is no confirmed evidence that all of these ideas are coming, but the expanded theme architecture provides the technical and design foundation for such possibilities.
Performance Will Matter More Than It Seems
Animated wallpapers also introduce another consideration: performance.
A static image requires relatively little processing once displayed. Animation, on the other hand, can require continuous rendering.
That makes optimization particularly important on older iPhones or devices operating under battery-saving conditions.
WhatsApp will need to ensure that animated themes do not noticeably increase battery consumption, device temperature, memory usage, or scrolling latency.
The decision to use slow animation could help reduce those concerns.
Less movement generally means less visual complexity and fewer reasons for the interface to constantly redraw large portions of the screen.
Deep Analysis: How to Evaluate the New Theme Experience
The most important technical questions are not simply whether an animation looks attractive. Developers and advanced users should examine rendering performance, memory consumption, battery impact, contrast, accessibility, and frame stability.
On Android test devices, developers can use ADB to monitor the application while testing similar UI behavior:
adb shell dumpsys gfxinfo com.whatsapp
This can provide graphics and rendering statistics that help identify performance problems during intensive interface activity.
For broader application-level information, testers can inspect the WhatsApp process:
adb shell dumpsys meminfo com.whatsapp
A comparison between a static theme and an animated theme could reveal whether the new visual experience introduces a measurable memory increase.
Battery behavior can also be examined during controlled testing:
adb shell dumpsys batterystats –charged
After reproducing the same workload, developers can collect battery statistics and compare the results.
For frame-performance analysis,
adb shell dumpsys gfxinfo com.whatsapp reset
The objective is not to prove that
On iOS, developers can perform equivalent profiling through Apple’s Instruments tooling, focusing particularly on CPU activity, memory allocations, animation rendering, energy impact, and frame responsiveness.
The critical metric is not simply whether the animation works.
The real question is whether users can forget that it is there.
If the wallpaper consumes excessive resources or causes visible frame drops, the feature will feel less like personalization and more like unnecessary overhead.
Why Automatic Color Selection Is Technically Important
Automatic bubble-color selection also deserves closer attention.
A theme engine must understand the relationship between the wallpaper and foreground interface elements.
In simplified terms, the system needs to evaluate the visual characteristics of the background and select a foreground color that maintains sufficient contrast.
Conceptually, a theme system could follow logic similar to:
load wallpaper
↓
analyze background luminance
↓
select compatible bubble palette
↓
calculate readable text color
↓
apply theme
↓
validate contrast
The exact implementation used by WhatsApp is not publicly documented, but this illustrates why automated theme selection is more complicated than simply changing a hexadecimal color value.
The system needs to preserve readability across different visual environments.
The Accessibility Question Cannot Be Ignored
Animated wallpapers should also provide appropriate accessibility considerations.
Users who prefer reduced motion should ideally have an experience that respects their system-level preferences.
A mature implementation could reduce or disable animation when the operating system indicates that the user prefers reduced motion.
This would allow WhatsApp to offer expressive themes without forcing motion on people who do not want it.
The same principle applies to contrast and text readability.
Customization should remain optional.
What This Means for Everyday WhatsApp Users
For ordinary users, the biggest difference will be simple: WhatsApp chats may soon feel more personal.
Someone who prefers colorful interfaces can choose a Featured theme.
Someone who loves the traditional WhatsApp appearance can use Doodle.
Someone who wants the conversation to remain completely dominant can choose Minimal.
That range is arguably more valuable than any single wallpaper.
The feature gives users different visual personalities without forcing everyone into the same design.
What This Means for
The theme expansion also hints at where
The platform has historically prioritized functionality over visual customization, but modern messaging applications increasingly compete on experience as much as features.
WhatsApp is already one of the
Themes are a relatively low-risk way to achieve that.
They change the atmosphere without changing the fundamental messaging experience.
What Undercode Say:
- A Small Feature With a Larger Purpose
WhatsApp’s upcoming theme expansion may look like a simple cosmetic update, but it reflects a much broader change in how the platform approaches personalization.
2. The Three Categories Make Sense
Featured, Doodle, and Minimal give users three understandable visual directions instead of dumping an enormous collection of options onto the screen.
3. Animated Wallpapers Are the Attention Grabber
The animated Featured themes will probably generate the most excitement because they make the interface feel noticeably different.
4. Restraint Is the Right Strategy
Slow animation is a much better choice than aggressive motion because conversations should remain the primary visual focus.
5. Accessibility Should Be Built In
The system should respect reduced-motion preferences and avoid creating visual experiences that make reading unnecessarily difficult.
- Automatic Colors Are a Smart Design Choice
Users should not need to understand color theory to make a theme readable.
7. Contrast Is More Important Than Style
A beautiful theme becomes useless if the text cannot be read comfortably.
8. Minimal Themes Could Become Surprisingly Popular
Not every user wants personalization to mean more visual noise.
9. Doodle Protects
The traditional doodle aesthetic gives longtime users a familiar option inside the new system.
10. Cross-Platform Consistency Matters
Bringing the same basic theme architecture to iOS and Android can reduce fragmentation.
11. The Feature Could Strengthen
Personalization can make an application feel more individual and less like a generic utility.
12. Performance Will Determine Its Success
Animated interfaces must remain smooth without creating unnecessary CPU, GPU, memory, or battery costs.
13. Older Devices Are an Important Test
A feature that works beautifully on a new iPhone but performs poorly on older hardware would create an uneven experience.
14. Battery Consumption Could Become a Complaint
Users may tolerate animation until they notice it affecting battery life.
15. Slow Motion Helps Solve Two Problems
It can reduce visual distraction while potentially lowering rendering demands.
16. Server-Side Activation Explains the Confusion
A feature can exist inside a beta build while remaining invisible to testers.
17. Development Does Not Mean Guaranteed Release
WhatsApp can still change or cancel the feature before public rollout.
18. The Theme Categories Could Expand
Three categories today could become a much larger customization ecosystem tomorrow.
19. Seasonal Themes Are an Obvious Possibility
Holiday, event, and special-edition themes could eventually fit naturally into the system.
20. Personalization Could Become More Intelligent
Future theme recommendations could potentially adapt to user preferences.
21. WhatsApp Must Avoid Overcomplication
More customization is useful only if users can understand it quickly.
22. Simplicity Remains a Competitive Advantage
WhatsApp should not sacrifice its straightforward interface in pursuit of visual novelty.
- The Bubble System Is More Important Than It Looks
Automatic color coordination is what can make complex wallpapers remain usable.
24. Good Design Should Feel Invisible
Users should notice that their chat looks better without struggling to read it.
25. The Minimal Category Shows Strategic Thinking
Offering an option to remove visual complexity demonstrates that WhatsApp understands different user preferences.
26. Animated Wallpapers Will Need Testing
Beta testing should measure more than appearance. It should examine performance, battery use, accessibility, and stability.
27. Developers Should Watch Frame Rates
Visual stuttering would undermine the entire purpose of adding animation.
28. Memory Management Matters
Large or poorly optimized animated assets could increase memory pressure.
29. Theme Assets Should Be Efficient
Compression, caching, and appropriate animation techniques will be essential for keeping the feature lightweight.
30. Network Usage Could Also Matter
If WhatsApp eventually offers downloadable theme collections, asset delivery and caching will become important.
- Privacy Is Less of a Concern Here
Unlike AI-powered features or cloud-based personalization, basic visual themes can operate largely as local interface customization.
- The Feature Is Unlikely to Change Messaging Itself
The biggest impact will be on the experience surrounding conversations rather than the underlying messaging system.
33. This Could Make WhatsApp Feel Younger
A platform with billions of users cannot completely redesign itself every year, but small visual improvements can prevent it from feeling stagnant.
- iOS Users Should Expect More Gradual Changes
Apple’s ecosystem places different design and performance expectations on applications, making careful implementation particularly important.
35. Android Development Provides a Useful Preview
The Android version gives observers an indication of the direction WhatsApp is taking before the iOS implementation becomes available.
- The Feature Could Encourage More Frequent Customization
Users who previously ignored wallpaper settings may experiment once the options become easier to discover.
37. Group Chats Could Benefit
Different visual styles could eventually help users distinguish important conversations more easily, although per-chat customization rules remain subject to WhatsApp’s final implementation.
- WhatsApp Is Moving Beyond a One-Size-Fits-All Interface
The theme system represents another step toward letting users shape their own experience.
- The Best Feature May Be the One Users Barely Notice
If WhatsApp succeeds, people will see a more attractive interface without feeling distracted by it.
- The Real Test Begins With Beta Users
Once the feature is enabled for testers, real-world feedback will reveal whether animated themes feel useful, enjoyable, or simply unnecessary.
✅ The iOS Theme Expansion Is Under Development
The supplied report identifies WhatsApp beta for iOS 26.31.10.74 as the build where the new theme work was discovered. The feature is described as being under development rather than generally available.
✅ Three Theme Categories Are Planned
The reported categories are Featured, Doodle, and Minimal. These categories represent different visual approaches, ranging from expressive designs to a deliberately plain interface.
✅ Animated Wallpapers Are Part of the Featured Concept
The reported Featured category includes animated wallpapers with slow, gradual movement. The important distinction is that this is a feature being developed, not a feature currently available to every iPhone user.
❌ A Public Release Date Has Not Been Confirmed
There is currently no confirmed public rollout date in the supplied information. Any specific claim that the themes will arrive on a particular day should therefore be treated as speculation.
❌ Installing the Latest TestFlight Build Does Not Guarantee Access
The discovery of code or interface elements inside a beta does not mean WhatsApp has enabled the feature for all testers. WhatsApp can control feature availability separately from the application version.
✅ Automatic Bubble-Color Selection Fits the Reported Design
The planned system is described as automatically choosing bubble colors based on the selected theme. This is intended to maintain visual consistency and readability.
Prediction
(+1) WhatsApp Will Expand Chat Personalization Further
The direction of development strongly suggests that chat customization will become a more important part of WhatsApp’s interface strategy. If the three-category system performs well during testing, WhatsApp is likely to expand the theme library and introduce additional visual styles over time.
The most probable evolution is not an explosion of complicated customization controls, but a curated collection of themes that users can activate with minimal effort.
Animated wallpapers are likely to remain optional, while Minimal and classic designs will continue to serve users who prioritize readability and simplicity.
(+1) Cross-Platform Theme Parity Will Become More Important
Because WhatsApp is developing similar theme functionality for Android and iOS, users can reasonably expect the company to push toward greater visual consistency between platforms.
That does not mean every technical implementation will be identical, but the basic experience should increasingly feel like the same WhatsApp regardless of whether the conversation is opened on an iPhone or Android device.
(+1) Accessibility Could Become a Major Differentiator
If WhatsApp properly integrates reduced-motion behavior, contrast-aware colors, and lightweight animations, the company could turn a seemingly cosmetic feature into an example of responsible interface design.
The strongest version of this feature will not be the one with the most impressive animation.
It will be the one that gives users personality without making conversations harder to read.
The Bigger Picture
WhatsApp’s upcoming iOS chat-theme expansion is a reminder that major applications do not always evolve through dramatic redesigns. Sometimes the most meaningful changes arrive quietly, through small features that gradually reshape how users experience the platform.
Featured themes could bring movement and personality.
Doodle themes could preserve familiarity.
Minimal themes could keep the interface clean.
Automatic bubble colors could make the entire system easier to use.
And if WhatsApp gets the balance right, these additions will not make the application feel complicated. They will simply make it feel more personal.
For now, iPhone users will have to wait. The new themes remain under development, and WhatsApp has not announced when they will reach beta testers or the stable release.
But the direction is already clear: WhatsApp is slowly moving from a one-style-fits-everyone messaging interface toward a more customizable experience — and animated wallpapers may be the beginning of that transformation.
