The wait is over for Xiaomi users who have been following the company's movements for months. The Chinese firm has launched the global beta of HyperOS 4, a version that comes with significant new features and is now beginning to roll out beyond its domestic market. This move comes exactly one month after the testing program began in China, and the first selected users can now request access.
This international rollout is especially relevant for the European market, as the beta includes both the Global and EEA versions of the devices. This means that users with a device purchased in Spain will be able to try the new system before the stable version is released. However, not everyone will have immediate access, as the company has established a phased rollout that will expand over the coming days.
The first models to receive the beta
The first batch of devices now eligible for the beta program includes the Xiaomi 17, the Xiaomi 17 Ultra, and the Leica Leitzphone powered by Xiaomi . These three phones are the company's current flagship models and, as usual, will be the first to receive new features. Applications are submitted through the Xiaomi Community app, following the path 'ME > Beta testing > Recruiting test' and completing a questionnaire.
As confirmed by the brand itself, slots for this first round are limited. Once Xiaomi approves the application, the phone will receive the beta update via OTA, although the company recommends manually checking availability by going to Settings, About phone, and tapping on the version number. It is also necessary to have the latest version of HyperOS 3 installed before updating.
More models available from September 17th
It doesn't stop at just three phones. Xiaomi has already announced a second batch of devices that will be added to the program starting September 17th . This time, the lucky ones will be the Xiaomi 17T, Xiaomi 17T Pro, Xiaomi 15, and Xiaomi 15 Ultra. The latter two have been officially sold in Spain for some time, which represents a golden opportunity to try HyperOS 4 on a European device before the stable update arrives.
With this expansion, the global beta now includes seven high-end phones. The company hasn't given a specific date for the stable version, but all indications point to it arriving between November and December of this year, following the pattern of previous releases. Meanwhile, users not on this list will have to wait for future expansions, which will likely be announced in the coming months.
How to request access and what risks are involved
The registration process is simple but requires meeting a few requirements. In addition to owning one of the compatible models, the user must be a member of Xiaomi's Mi Pilot program , a testing system managed by the Community itself. Once the application is accepted, the update is rolled out gradually, so there may be a slight wait before it appears on the phone.
But be aware, this beta version isn't for everyone. As it's a development version, you may experience unexpected app crashes, performance issues, and higher than usual battery drain. Xiaomi strongly recommends backing up your data and avoiding installing it on your primary phone if you rely on it for work or everyday use.
The most important warning is that once the beta is installed, you cannot revert to HyperOS 3 via an OTA update. To return to the previous version, you will need to flash your device, a process that can erase all stored data. In other words, anyone who decides to join the beta should be sure they want to stay on it for a while.
As for new features, HyperOS 4 arrives with a revamped visual design, featuring glass effects and transparencies inspired by 'liquid glass'. It also includes a new smart notification system that automatically groups notifications, improvements in system fluidity, and more efficient resource usage. Changes also affect the camera, with improvements to HDR processing and greater responsiveness.
The download size varies by region. While the Chinese beta exceeds 8 GB, the global version is around 2,8 GB, which has raised some questions about which features are included in this first phase. According to some users, the final version will be similar in size to the Chinese one, so we'll have to wait for the stable update to see all the new features.
With everything now in place, the global beta of HyperOS 4 is a reality , and Spanish users with a Xiaomi 15 or 15 Ultra will soon have the opportunity to try it. The company continues to make progress in bringing its new software to every corner of the world, and this release is a clear indication that the stable version is getting closer.
