Xiaomi Opens HyperOS 4 Beta Testing to Global Users
Beta software is incomplete. Bugs are expected.

So Xiaomi's asking people to test HyperOS 4 before it's done. What's the actual scope here—how many devices are we talking about in the first wave?
Mimi
Three models to start: the Xiaomi 17 Ultra, the Leica Leitzphone, and the standard Xiaomi 17. Then on September 17, they're bringing in four more—the 17T, 17T Pro, 15, and 15 Ultra. So it's a staged rollout.
Luke
Do we know how many people they're accepting into the beta? The source doesn't say. It just says they're recruiting—could be hundreds, could be thousands.
Mimi
Fair point. We know the process: you go into the Community app, fill out a questionnaire, and if you're accepted, you get the update over the air. But the actual size of the program isn't disclosed.
Mark
What happens if someone gets in and then realizes it's too buggy to live with?
Mimi
That's the tricky part. You can go back to HyperOS 3, but you have to manually flash the firmware. You can't just roll back through the normal update system.
Luke
Which means most casual users probably won't do it. They'll be stuck.
Mimi
Exactly. It's a barrier. Xiaomi's essentially saying: if you're not comfortable with a command line and downloading firmware files, don't join the beta.
Mark
Does Xiaomi say anything about what HyperOS 4 actually does differently?
Luke
No. The source doesn't mention features, improvements, or what's new. We only know it exists and that they want testers.
Mimi
That's a gap. We're reporting on the recruitment, not the product itself. The actual substance of the update is still unknown to us.
El Pulso
- Xiaomi has thrown open beta enrollment for HyperOS 4, creating immediate urgency for early adopters eager to be first inside the next generation of its operating system.
- The program launches with only three devices — Xiaomi 17 Ultra, Leica Leitzphone, and Xiaomi 17 — creating a narrow window that will widen on September 17 when four more models become eligible.
- Enrollment requires navigating the Xiaomi Community app and completing a questionnaire, with some applicants facing an additional account verification hurdle before gaining access.
- Beta participants must reckon with a significant catch: abandoning the beta means manually flashing firmware on a computer, not a simple tap-to-rollback — a technical commitment that raises the stakes of signing up.
- Xiaomi is explicit that bugs are expected and recommends testers avoid using enrolled devices as daily drivers, framing participation as a contribution to the software's future rather than a seamless upgrade.
In the ongoing rhythm of software evolution, Xiaomi has opened its doors to early adopters willing to trade the comfort of stability for a glimpse of what comes next. Beginning in September 2026, global and European users with select Xiaomi 17 series devices may enroll in the HyperOS 4 beta program — a collaborative act of trust between a company refining its vision and users willing to inhabit unfinished territory. A second wave of eligible devices arrives on September 17, widening the circle of participation while reminding us that progress, by nature, arrives imperfect before it arrives complete.
Xiaomi is inviting global and European users into the early stages of HyperOS 4, opening beta enrollment for a select group of devices ahead of the software's official release. The program begins immediately for owners of the Xiaomi 17 Ultra, the Leica Leitzphone by Xiaomi, and the standard Xiaomi 17 — with a broader expansion planned for September 17, when the Xiaomi 17T, 17T Pro, Xiaomi 15, and Xiaomi 15 Ultra will also become eligible.
Joining is relatively straightforward: applicants open the Xiaomi Community app, navigate to their profile, and complete a beta testing questionnaire. Some participants may need to verify their accounts before being accepted. Once approved, the beta arrives as a standard over-the-air update — familiar in delivery, but different in nature.
The critical caveat is what happens if you change your mind. Unlike a typical software update, there is no simple rollback to stable HyperOS 3. Reverting requires manually flashing firmware using a computer — a process that demands both technical confidence and advance preparation. It is a commitment that Xiaomi wants prospective testers to understand clearly before enrolling.
As with all beta software, imperfection is the point. Bugs, inconsistent performance, and incomplete features are to be expected, and Xiaomi recommends that participants keep a separate primary device. The exchange on offer is straightforward: stability for early access, and personal convenience for the chance to help shape what millions will eventually use.
Xiaomi is opening the doors to its next major operating system update. Starting now, the company is recruiting beta testers for HyperOS 4 across global and European markets—a chance for early adopters to run the software before its official release, provided they own one of the qualifying devices and are willing to accept the risks that come with unfinished code.
To join, you need a Xiaomi 17 Ultra, the Leica Leitzphone by Xiaomi, or a standard Xiaomi 17. The enrollment process is straightforward: open the Xiaomi Community app, navigate to your profile, select Beta testing, then choose Recruiting test. From there, you'll fill out a questionnaire. Xiaomi notes that some beta versions may require account verification before you're accepted into the program.
Once approved, the beta build arrives as an over-the-air update, just like a normal software push. But there's an important caveat: if you decide the beta isn't for you and want to return to the stable version of HyperOS 3, you can't simply roll back through the standard update mechanism. Instead, you'll need to manually flash the firmware—a more technical process that requires downloading files and using a computer. This is a commitment worth understanding before you sign up.
The initial wave of recruitment is limited to those three models, but Xiaomi is planning to expand the program on September 17. At that point, the Xiaomi 17T, Xiaomi 17T Pro, Xiaomi 15, and Xiaomi 15 Ultra will become eligible for beta enrollment. This phased approach allows Xiaomi to gather feedback from a smaller, more manageable group before bringing in a larger pool of testers.
Beta software, by definition, is incomplete. Bugs are expected. Performance may be uneven. Features might not work as intended. Xiaomi is explicit about this: the company recommends that beta testers not use these devices as their primary phones. If you're considering joining, the calculus is simple—you're trading stability and reliability for early access to new features and the chance to help shape the software before it reaches the general public.
