Xiaomi’s Latest HyperOS Bug Report: What’s Fixed and What’s Still Broken

Xiaomi has published a new weekly bug report detailing fixes already shipped and issues still under investigation across several HyperOS devices. The fixes address autofocus failures on the Xiaomi 17 Ultra, incorrect battery capacity readings on the Xiaomi 13, display artifacts on the Redmi K90, and other problems. However, the report also acknowledges unresolved bugs — including NFC failures on the Redmi K70 and abnormal system-service load on the Redmi K90 Pro Max — that owners will have to wait on. All listed firmware builds currently apply to the Chinese market; Xiaomi says fixes should eventually reach global firmware, but no specific timeline has been given.

Xiaomi has released another bug-fix report for HyperOS

Bugs already fixed in HyperOS

The following fixes are available now in the listed firmware builds. Xiaomi notes that while bugs are verified on specific devices, other models experiencing similar issues may also receive the same patches:

• Xiaomi 17 Ultra (build 3.0.305.5) — autofocus failure when shooting with the telephoto lens in certain scenes has been resolved.
• Xiaomi 17 Max (3.0.304.0) — the quick-edit function now correctly applies wallpapers to the lock screen again.
• Xiaomi 17T Pro (3.0.308.0) — icon shape and color distortions in certain situations have been corrected.
• Xiaomi 13 (3.0.304.0) — incorrect battery capacity readings in some cases have been fixed.
• Redmi K90 (3.0.305.0) — white bars appearing simultaneously on both sides of the display have been eliminated.

The autofocus fix on the Xiaomi 17 Ultra is arguably the most significant, given that it is the company’s flagship camera phone and was struggling with something as fundamental as locking focus on a subject. The battery indicator fix on the Xiaomi 13 is also notable for anyone who relies on the charge reading to plan when to plug in.

Bugs still under investigation

Some HyperOS bugs remain unresolved

Xiaomi also listed bugs that are acknowledged but not yet fixed. If you own one of these devices and are experiencing the described behavior, a fix is not yet available:

• Redmi K90 Pro Max (3.0.306.0) — abnormal load from system services in certain situations.
• Redmi K90 Max (3.0.311.0) — fan-control malfunction under certain conditions.
• Redmi K80 (3.0.303.0) — spontaneous disconnection from a tablet when tethering.
• Redmi K70 (3.0.306.0) — NFC failure in some cases, affecting contactless payments and tag scanning.
• Redmi Turbo 4 (3.0.302.0) — brightness issues when switching the Kuaishou floating window.

The NFC failure on the Redmi K70 is particularly disruptive because it can prevent contactless payments and NFC tag reading entirely. Owners affected by this bug will need to wait for a future firmware update.

When will fixes reach global firmware?

It is important to set expectations: all firmware builds listed in this report are for the Chinese market. Xiaomi has indicated that confirmed bug fixes should eventually be included in global firmware, but no specific dates have been announced. Global users should watch for the next scheduled HyperOS updates, as fixes are likely to arrive bundled with routine updates rather than as standalone emergency patches.

Should you update now?

It may be worth checking for updates manually

If your device is on the fixed list and you have been experiencing one of the described bugs, updating makes sense. You can manually check for new firmware in your system settings rather than waiting for an automatic notification.

If your phone is working normally and you have not encountered any of the listed issues, there is no urgency. This is a targeted bug-fix report, not a major feature update, and it will not directly affect the majority of users.
