1. Soft Light Glass Design

The most noticeable change in Xiaomi HyperOS 4 is its new Soft Light Glass visual design.

This interface introduces refined transparency, softer lighting effects, improved depth, and more visually appealing transitions.

Instead of making everything look completely flat, Xiaomi uses layered visual elements to create a more modern appearance.

Key design improvements include:

• Glass-inspired interface elements.
• Dynamic lighting effects.
• Improved transparency.
• Refined visual hierarchy.
• Smoother transitions between menus.
• More polished system animations.

The overall design gives HyperOS 4 a fresh identity and makes everyday interactions feel more modern.

2. Improved Lock Screen Customization

Xiaomi has also improved lock screen personalization.

Users can enjoy more flexible clock styles, adjustable typography, and better visual arrangements.

The redesigned lock screen allows users to create a more personalized appearance without relying entirely on third-party applications.

Depending on the supported device, users can expect:

• Flexible clock sizing.
• Variable typography.
• More attractive visual layouts.
• Improved lock screen presentation.

These changes are particularly useful for people who enjoy customizing their smartphones.

3. Smarter Notifications and Widget Stacking

Notifications and widgets are essential parts of the smartphone experience.

HyperOS 4 introduces notification stacking to create a cleaner notification area. Instead of displaying everything in a crowded layout, notifications can be organized into a more manageable structure.

Widget stacking is another useful addition.

It allows users to organize multiple widgets in a smaller space and switch between them more efficiently.

This can help keep the home screen organized without sacrificing quick access to important information.

4. Resizable Home Screen Folders

Another interesting feature is improved home screen folder customization.

HyperOS 4 introduces more flexible folder resizing options on supported smartphones.

Users can organize applications according to their preferences and create a cleaner home screen.

For example, someone who frequently uses social media, photography, gaming, and productivity applications can organize them into larger or smaller folders.

This is a practical improvement for people who prefer a personalized home screen.

Performance and Speed: Is HyperOS 4 Faster?

Performance is one of the most important aspects of any smartphone operating system.

A beautiful interface means very little if applications open slowly or animations become inconsistent during everyday use.

Xiaomi says HyperOS 4 introduces several system-level optimizations to improve responsiveness.

Faster Application Launching

Xiaomi also reports improvements in application launching and camera responsiveness.

According to Xiaomi’s internal laboratory comparisons on the Xiaomi 17 Ultra:

• The total hot-launch time for 30 applications after nine hours of use decreased from 40.3 seconds to 36.8 seconds.
• Rear-camera HDR photo capture time improved from 313.38ms to 240.16ms.
• Camera cold-launch time decreased from 1,043.6ms to 808.8ms.

These are manufacturer-reported results rather than independent benchmark findings. Actual performance will depend on the smartphone model and usage conditions.

Overall, the performance improvements look promising, particularly for users who regularly switch between applications.

These tools are designed to make long recordings easier to understand and review.

AI Translation

AI Translate Conversation aims to make communication between people speaking different languages easier.

This feature can be particularly useful for travelers, international students, and people working with overseas clients.

However, supported languages, devices, and regional availability may vary.

AI Gallery Search

Finding a particular photograph in a large gallery can be frustrating.

HyperOS 4 introduces AI Gallery Search to help users locate images more easily using intelligent search capabilities.

Instead of manually scrolling through thousands of pictures, users can search for relevant content using supported search options.

AI Creativity Assistant

Xiaomi also provides AI-powered creative tools for supported devices.

These features are designed to help users edit images and explore different creative possibilities directly from their smartphones.

The availability of individual AI tools depends on the device, language, and region.

Privacy and Security Improvements

Smartphones contain personal photographs, messages, financial information, and other sensitive data.

For this reason, privacy and security are important considerations when evaluating a new operating system.

Xiaomi HyperOS 4 introduces additional security technologies, including:

• Improved data protection mechanisms.
• Edge-to-cloud AI data security.
• On-device privacy storage.
• Secure communication channels.

Xiaomi describes these technologies as part of its broader effort to strengthen data protection.

However, the availability of some advanced privacy features is limited to supported devices and services.

Users should still follow standard security practices, such as installing official updates, using strong screen locks, and avoiding suspicious applications.

Xiaomi HyperOS 4 on Tablets and the Xiaomi Ecosystem

HyperOS is not limited to smartphones.

Xiaomi continues to develop its software platform for tablets and other connected devices.

HyperOS 4 brings improvements to tablet application layouts, navigation, and multitasking.
