The POCO F7 Pro uses an ultrasonic in-display fingerprint sensor. And it undergoes strict professional inspections before leaving the factory, so you can use it with confidence.
If you notice this issue when using the phone, please refer to the following information:
1. The phone uses an ultrasonic in-display fingerprint sensor, which is more sensitive and improves the unlocking experience at night. But there are certain requirements for screen protectors;
2. Films that are not certified by Xiaomi will have a serious impact on the fingerprint-unlocking experience. To ensure the unlocking experience, please use the official protective film;
3. If the fingerprint unlocking is abnormal after applying the third-party tempered film, please tear off the film and re-enter the fingerprint for use. We sincerely appreciate your understanding and thank you for your continued use.
