Xiaomi has just opened recruitment for the global beta test of HyperOS 4, and users from Europe can also sign up – but for now, only with a handful of flagship models. Only owners of the latest flagships can sign up The first wave of recruitment consists of Xiaomi 17 Ultra, Xiaomi 17, and Leica Leitzphone, in versions for both the global market and the European Economic Area (EEA). A week later, on September 17, the scope will expand to include Xiaomi 17T Pro, Xiaomi 17T, Xiaomi 15 Ultra, and Xiaomi 15. Thus, not all models will enter the test at once – the manufacturer is rolling it out in groups. HyperOS 4 is coming to the world. Xiaomi launched tester recruitment Adam Kurfürst News Adam Kurfürst News Interested parties apply directly in the Xiaomi Community app via ME → Beta testing → Recruiting test, where they fill out a short questionnaire. The phone must be running the latest version of HyperOS 3, and the login account must match the one on your mobile. According to Xiaomi, the beta is an early version without a fixed release date, so even after approval, the update may not arrive immediately. What to watch out for before signing up? Xiaomi immediately warns that the beta is usually less stable than the final version and some third-party applications may behave erratically on it. Therefore, before installation, it recommends backing up data and assuming you can handle basic firmware flashing. The biggest catch is reverting. You cannot downgrade from HyperOS 4 beta to HyperOS 3 with a regular update – downgrading means flashing the firmware, ideally at an authorized service center, and you may lose data during that operation. Therefore, according to the manufacturer, it’s more worthwhile to test on a secondary phone than on your daily driver. HyperOS 4 is coming to the world.
