Why is there no fingerprint icon on the POCO F7 Pro lock screen?
If there is no fingerprint icon on the phone, please refer to the following information:
1. If you can add fingerprints on the POCO F7 Pro but encounter an issue where the fingerprint icon 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;
2. 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;
3. 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 icon is operational when the screen is locked. Thank you for your understanding and support.
