If the fingerprint sensor can be used on the old display, it can also be used after installing the new display. Q2: How to activate the fingerprint function of the new screen?Answer: After installation, you need to delete the old fingerprint and re-enter the new fingerprint. After entering the new fingerprint, use the password to unlock it for the first time. Turn on the screen again, and then use your fingerprint to unlock. The fingerprint function is activated. Q3: Why can’t the fingerprint function be used after installing the screen?Answer: Our screens can only be shipped after fingerprint testing. If the fingerprint cannot be used, there are two situations: 1. The fingerprint sensor is damaged or the fingerprint hole is not installed correctly. The motherboard link cable 1 or 2 is faulty. Please try to replace the above parts and then try to use fingerprints. If you have any questions, please contact store customer service.
