The Redmi K90 Pro Max (codename: Myron), also known globally as POCO F8 Ultra, was released in October 2025 as a flagship with Android 16 and Xiaomi’s new HyperOS 3 UI. Renowned for top-tier performance, an AMOLED display, and camera prowess, the device still sees real user concerns in 2025.
Users highlight issues with battery drain, stuttery UI in HyperOS, camera lens fogging, microphone glitches, aggressive background app management, and frequent “System Has Been Destroyed” boot errors, especially after failed or cross-region updates.
The latest firmware files, including the official Chinese and Xiaomi.eu (multilanguage) ROMs, aim to resolve many of these problems—patching bugs, improving stability, and keeping Google services compatibility for global users.
