Xiaomi is preparing to roll out a highly anticipated HyperOS 3 optimization update aimed at refining the user experience for its flagship devices. While the current HyperOS build introduced a wealth of new features, users have reported several UI and system-level bugs.

According to official Xiaomi software development reports, the upcoming patch will address these specific pain points across the Xiaomi 17 series, the Xiaomi 15 series, and the Redmi K90 Pro Max.

If you've been experiencing issues with your system keyboard, WeChat video calls, or AI assistants, relief is on the way. Here is a detailed breakdown of the upcoming fixes and how to prepare your device for the update.

Already Fixed: Xiaomi 17 Pro Max Rear Screen

Before diving into the upcoming patch, Xiaomi has confirmed that a hotfix has already been deployed for a major camera bug on the Xiaomi 17 Pro Max.
Previously, users attempting to use the rear display as a viewfinder for high-resolution selfies experienced a broken or frozen preview. If you own a Xiaomi 17 Pro Max, navigate to your updater app now—installing the latest available security patch will resolve this rear-screen photo preview issue immediately.

Upcoming HyperOS 3 Fixes by Device

The next major OTA (Over-The-Air) update will target specific software anomalies. Here is what the development team is currently finalizing:

Xiaomi 17 Series Improvements

The flagship Xiaomi 17 lineup will receive the bulk of the optimizations, primarily focusing on input methods and third-party app integration.


System Keyboard Enhancements: The update will fix a visual bug where the advanced texture input method was rendering improperly, making keys difficult to see.


Additionally, the voice-to-text dictation feature within the native keyboard—which had been failing to transcribe speech will be fully restored.


WeChat Floating Window Glitch: Users previously reported that after hanging up a voice or video call on WeChat, the floating call window would remain stuck on the screen. The new update forces the window to close correctly.


Weather App Syncing: The native Weather widget and app will receive a background refresh fix, ensuring your climate data updates in real-time without requiring a manual app launch.


AI Assistant & 9-Key Pinyin: A specific input box bug causing erratic typing behavior when using the 9-key Pinyin layout to summon the AI assistant has been squashed.


Xiaomi 15 Series Improvements

Users of the older, yet highly popular, Xiaomi 15 series are also getting critical quality-of-life improvements:


Display Brightness: The update calibrates the auto-brightness sensor algorithm, resolving an issue where the screen would abnormally dim or brighten in specific ambient lighting conditions.


Super AI Trigger: The shortcut to activate Super AI by long-pressing the power button was failing in certain apps and scenarios. This trigger mechanism has been stabilized.


WeChat GIF Bug: A bizarre rendering issue that caused animated GIFs sent via WeChat to appear upside down or reversed will be corrected.
Redmi K90 Pro Max


Xiao Ai Timetable Stability: The update patches a critical memory leak that was causing the Xiao Ai Timetable application to crash unexpectedly during daily use.


How to Prepare for the HyperOS 3 Update


To ensure a seamless transition when the update arrives on your device, we recommend following these expert best practices:


Back Up Your Data: While OTA updates rarely cause data loss, it is always best practice to back up your photos, contacts, and documents to Xiaomi Cloud or a local PC.


Charge Your Battery: Ensure your phone is charged to at least 50% before initiating the installation to prevent the device from powering off during the system rewrite.
Free Up Storage Space: System updates require room to unpack. Aim to have at least 5GB of free internal storage available.

How to Check for the Update


Xiaomi typically rolls out updates in staged batches based on region. To manually check if the update has reached your device:
Open your phone's Settings.


Tap on About Phone.


Tap on the HyperOS logo/version at the top of the screen.
Click Check for Updates.


Stay tuned for further coverage as we test the battery life and performance metrics of this new HyperOS build once it officially drops.
