Emir BardakçıThe issue, where swiping down to open a small pop-up window in HyperOS Beta, sometimes resulted in unresponsive message notification cards, has been dealt with by Xiaomi. This problem had caused temporary freezes in some scenarios, especially when users were in the middle of gameplay. The fix will help improve system fluidity to further enhance user experience on Xiaomi devices.
What was the Notification Freeze issue?
In the latest HyperOS 3 update some users found a rare bug: when pulling down a message notification card to open a small floating window, the interface would get stuck. It only appeared most of the time when a free-form window was switched to while receiving a new message. The bug is not common but affects usability during dynamic scenarios, such as gaming.
Why It Happened
The freeze was related to the system’s free-form window rendering process. When a message was received during full-screen activity, transition logic between a notification card and a small pop-up window didn’t manage to finish properly and thus caused an interface lock. Fortunately, Xiaomi’s engineering team was able to isolate the cause in the Beta logs and quickly prepared a corrective patch.
Fixes and Improvements by Xiaomi
Xiaomi has now issued an update to fix this behavior. The patch improves how HyperOS handles layered UI transitions, making message cards smoothly expand into popup windows without interrupting foreground apps. It is an important refinement that makes multi-windowing more robust, especially for those who use floating windows to handle messages while in-game or consuming media.
Additional Optimizations
With this fix, Xiaomi also implemented:
- More consistent animation timing in free-form window transitions
- Improved stability when switching from full-screen apps
- Faster rendering of small pop-up windows during multitasking
These tweaks further reinforce Xiaomi’s commitment to responsiveness and reliability within the Beta program for HyperOS.
How Users Can Update
This fix is part of the latest HyperOS Beta rollout. Users already on the Beta channel will automatically receive the patch. Meanwhile, users of Xiaomi system apps can update or manage relevant services via HyperOSUpdates.com, or on the Play Store through the MemeOS Enhancer app, which also grants access to hidden Xiaomi features and system app upgrades.
This fixed notification card freeze issue shows how Xiaomi responds quickly to feedback from its users and continuously refines the HyperOS environment. Xiaomi not only ensures smoother transitions and prevents interface freezes in daily scenarios but also significantly enhances gaming performance across all Xiaomi products.
