Chosen Solution

Dear, I repaired my ipad mini 4 for the first time, I have an problem with the fingerprint function. When i replaced the home button and try to test the screen and the function ,my fingerprint does not respond anymore. I checked in the touch id options and it is not turned of so i think its not broken, also i can just switch it on and off. When i had this problem with an iphone the ios gave an error that the touch id will not work. Is there any solution for this or what i might did wrong.

did you use the original home button, as other home buttons wont let you use touch id, only apple can supply home buttons with touch id
