Installation Notes
Before you slot it in, give the new cable a quick test if you can. When handling, try to use an anti-static wrist strap to avoid any sneaky electrical surprises. Be gentle with the ribbon—don’t fold it sharply beyond a 90-degree angle. Take your time, follow a good guide for your model, and you’ll have that fingerprint sensor back in action.
