Fingerprint unlock suddenly stopped working on your Poco X3? The sensor flex cable is often the culprit, and swapping it out can bring your phone back to life.
What You’re Getting
This black fingerprint sensor flex cable is made for the Xiaomi Poco X3 and Poco X3 NFC. Each unit is checked for good condition before it leaves our warehouse, so you aren’t guessing whether it works. It’s a direct replacement for the part that reads your finger and talks to the motherboard.
Compatibility
This cable is listed for the Poco X3 and Poco X3 NFC only. Double-check your model number in your phone’s settings before ordering, since the fit varies between Xiaomi handsets. If your device is a different Poco or Redmi model, this part won’t line up correctly.
Installation Notes
Power the phone off fully before you begin, and work on a clean, static-free surface. Wear an ESD strap so you don’t zap the sensor. Take care when lifting the connector, and never bend the cable past 90 degrees, or the thin traces can crack. Professional installation is the safest route if you’re not comfortable opening the phone, since mistakes can damage the board or the screen.
