How to Fix Xiaomi Phone Overheating During Normal Use

A Xiaomi fingerprint scanner not working is usually caused by a dirty sensor, outdated HyperOS software, corrupted fingerprint data, or a hardware fault after impact or moisture exposure. To fix fingerprint HyperOS issues, clean the sensor, re-add fingerprints, check security settings, update software, and test the scanner before considering a reset or repair.

Steps

Clean the fingerprint area and remove accessories.
Wipe the sensor or power-button scanner with a dry microfiber cloth. Remove thick cases, screen protectors covering the sensor area, and any dirt, oil, or moisture from the finger.
Delete saved fingerprints and register again.
Open fingerprint settings, remove old entries, and add at least two scans of the same finger. Register the finger in normal, dry condition and cover edge angles during setup.
Check HyperOS updates and restart the phone.
Install pending system updates, then restart the device. A fingerprint scanner fix often comes from a patch after a HyperOS update bug or temporary service error.
Confirm security settings are active.
Make sure a screen lock PIN, pattern, or password is set. On some Xiaomi models, fingerprint unlock is disabled after multiple failed attempts, after reboot, or when certain work-profile policies are enabled.
Test in Safe Mode or after resetting settings.
If the scanner stopped working after installing an app, boot into Safe Mode. If the issue remains, reset system settings or back up data before a factory reset.

Common Issues and Fixes

Issue	Likely Cause	Fix	Considerations
Fingerprint option missing in settings	System bug or unsupported sensor detection failure	Update HyperOS, restart the phone, and check CIT or hardware test if available	If the menu does not return, the sensor may not be detected properly by the system
Scanner unlocks slowly or fails often	Partial finger scan or dirty sensor	Delete old fingerprints, clean the scanner, and re-register the same finger twice	Edge-angle enrollment usually improves recognition speed and consistency
Fingerprint stopped working after update	Temporary HyperOS glitch	Restart the phone, install the next patch, or reset settings	Many update-related scanner problems are software-based and temporary
Sensor works only sometimes	Moisture, sweat, or micro-scratches	Dry the finger, avoid lotion, and test another enrolled finger	Environmental and skin conditions can affect fingerprint accuracy more than expected
No response from scanner at all	Hardware damage from drops or water	Run hardware diagnostics and arrange service if the sensor fails every test	A factory reset will not repair physical sensor damage

Quick Tips

Side-mounted scanners: Side-mounted scanners on Xiaomi phones often fail when the power button is loose or physically worn.
In-display sensors: In-display sensors can become unreliable with thick tempered glass or poor screen protector adhesive.
After reboot: Fingerprint unlock may stay unavailable until the lock screen PIN or password is entered once.
Single finger failure: If only one finger fails, the problem is often skin dryness, cuts, or changing finger texture rather than the sensor.

Why is the Xiaomi fingerprint sensor not showing?

The fingerprint menu may disappear when the system fails to detect the sensor. Software corruption, incomplete updates, or hardware disconnection are common causes.

Does a factory reset fix fingerprint scanner problems on Xiaomi?

A factory reset can fix software-related fingerprint scanner fix cases. A reset does not repair a damaged or disconnected fingerprint sensor.

💡Protip:

Before resetting a Xiaomi phone for persistent fingerprint errors, a local backup is recommended. For broader device backup or file export, a phone management tool such as Dr.Fone can help preserve photos, videos, and other data first.
