Why is there no fingerprint scanner on the POCO F6 Pro when the screen is locked?
If you are able to add fingerprints on the POCO F6 Pro but encounter an issue where the fingerprint scanner does not appear when the screen is locked, it is due to the device’s security protection mechanism being triggered by a demagnetized or abnormal SIM card.
When the SIM card is demagnetized or not functioning correctly, the phone’s security system will restrict access to biometric authentication features, including fingerprint and face recognition, as a precautionary measure. This is done to prevent unauthorized access and protect your device’s security.
To resolve this issue, remove the problematic SIM card and replace it with a functional one. After doing so, restart your device and check if the fingerprint scanner is operational when the screen is locked.
If the problem persists despite using a proper SIM card, consider visiting the local after-sales center for further assistance.
