Tested replacement built for repair benches, this black fingerprint sensor flex cable is made for the Xiaomi Redmi 14C 4G. It restores the unlock function when the original ribbon has worn out, cracked, or stopped responding.
What You’re Getting
You receive one fingerprint sensor flex cable in black, matching the colour of the Redmi 14C 4G. Each unit is inspected and confirmed to be in good working order before it leaves our hands, so you aren’t guessing whether it will function once fitted.
Why This Part Works
The sensor sits on a thin flex ribbon that carries signals from the fingerprint reader to the motherboard. When that connection fails, the phone can’t recognise your touch at all. This replacement reconnects that link and brings back reliable unlocking, app authentication, and payment verification.
Installation Notes
Work on a clean, well-lit surface and keep small screws organised as you go. Wear an ESD strap to protect the internal chips from static discharge. Lift connectors gently and never bend the cable past 90 degrees, since sharp creases can break the copper traces. Test the sensor before fully reassembling the phone. Professional installation is recommended, especially if you haven’t opened a Xiaomi handset before.
