Fingerprint not unlocking your phone anymore? A worn or damaged sensor cable is often the culprit, and this in-display replacement brings your unlock back.
What You’re Getting
This is an in-display fingerprint scanning sensor flex cable designed for the Xiaomi Redmi K20, Redmi K20 Pro, Mi 9T Pro and Mi 9T. Each cable is checked for good condition before it leaves our shelves, so you get a unit that’s ready to fit straight out of the box.
Why This Part Works
The sensor sits under the display, so the cable carries the signal between the scanner and the motherboard. A fresh cable restores that link without touching the rest of your screen assembly. It’s a focused fix, not a full overhaul.
Compatibility
Check that your model number matches one of the four listed phones before ordering. The Redmi K20 and Mi 9T share a layout family, but the Pro variants are the ones named here, so confirm yours first.
Installation Notes
Professional fitting is the safest route, especially with the tiny connectors involved. If you’re going DIY, work on a clean, well-lit surface and wear an ESD strap so you don’t zap the sensor. Lift connectors gently and never bend the cable past 90 degrees, or you risk a hairline break. Test the fingerprint scanner before you fully reassemble the phone.
