IPhone 6s screen replacemnet made Touch ID stop working?

I repaired my IPhone 6s with a new screen carefully and making sure every cable is plugged in. The home button works perfectly it also senses just touching the home button like it is supposed to. But when I try to use my fingerprint instead of my passcode I get no response, it doesn't recognize I'm trying to sign in with my fingerprint. Also when I try to set a new finger print it doesn't read my finger print it just sits there acting like I haven't done anything yet. Is the LCD faulty or are there more checks I can do on my part?

Apple "marries" the TouchID sensor with the logic board. If you did a screen replacement but didn't re-use the home button from the original display, that is the issue. You have to use the original TouchID sensor in order for it to work.

  • Why is my iPhone 4's touch screen not working well? I have an iPhone 4, and has recently stopped working properly. When I unlock it, it will sometimes take at least 5 swipes to work. It's even worse when I try to put in my passcode. In the middle of playing a game or texting someone, the touch screen will stop working, and I can't tap. The home and power button still work just fine, but I need to power off and then back on again to get it working again. If anyone can help, it is greatly appreciated.
  • Why does my iphone stop working after I change the date and how can I stop it from doing that?

  • What's the difference between a international made iPhone and US made iPhone? I plan on buying or trading my iPhone 4 for a new iPhone 5C on Craigslist or at my local phone shop. Plus, can I flash a unlocked iPhone on to any carrier like PageOne or revol wireless?
  • My Iphone touch screen isn't working? I dropped it while bending over, and now whenever I go to slide to unlock, it doesn't move. When I go to power it off, the cancel works fine, but again, the slide bar won't work. I restarted it, and when I do this, it automatically brings up the passlock, and when I go to type it in, only the 1 - 2 - 3 and 5 work… So I can't unlock my iphone at all. Does anyone know what I can do to get it working?
