How to Fix Xiaomi Phone Stuck on Downloading Do Not Turn Off

Xiaomi Face Unlock not working after an update is usually caused by a disabled unlock setting, broken biometric data, camera permission changes, or a HyperOS system bug. In most cases, the fix is to re-enable face recognition, delete and add face data again, install pending patches, and confirm that lock screen security settings were not changed during the update.

Steps

1. Check whether Face Unlock is still enabled

   Open Settings > Passwords & security > Face unlock and confirm that face recognition Xiaomi settings are still active. Some updates reset biometric options or turn off lock screen unlock methods.

2. Delete existing face data and register again

   Remove saved face data, restart the phone, then add the face again in normal indoor lighting. Corrupted biometric files are a common reason for Xiaomi face unlock broken reports after a system update.

3. Install all pending system updates

   Open Settings > About phone > System update and install any small follow-up patches. Initial HyperOS or MIUI updates sometimes introduce bugs that are corrected by later fixes.

4. Check lock screen and privacy settings

   Confirm that screen lock is set to a supported method such as PIN, password, or pattern. Face unlock can fail if lock screen security was downgraded, changed by work profile policies, or restricted by privacy settings.

5. Clear camera-related conflicts

   Test the front camera in the Camera app. If the front camera is blurry, blocked, or not opening correctly, face unlock may not work because the sensor cannot verify facial data.

Common Issues and Fixes

• Face unlock toggle missing — likely cause: regional restrictions or unsupported firmware build — fix: change region only if officially supported, then restart and check biometric settings again.
• Face data cannot be saved — likely cause: corrupted facial profile after update — fix: remove old data, reboot, and set up face recognition again under stable lighting.
• Unlock works in apps but not on lock screen — likely cause: lock screen option disabled — fix: enable the specific face unlock action for screen unlocking inside security settings.
• Front camera opens but scanning fails — likely cause: dirty lens, screen protector shadow, or poor lighting — fix: clean the lens, remove obstruction around the selfie camera, and rescan in brighter light.
• Face unlock stopped after HyperOS update — likely cause: temporary software bug — fix: install the latest patch or reset settings if no hardware issue is present.

Quick Tips

Why did Xiaomi face recognition stop working after update?

Updates can reset biometric settings, corrupt saved face profiles, or introduce temporary software bugs. Re-adding face data and applying later patches resolves many cases.

Is factory reset necessary for Xiaomi face unlock broken problems?

Factory reset is not usually the first fix. Reset becomes useful only after settings checks, face data re-registration, and update patch installation fail.
