Touch ID/ Home Button issue after repair
I replaced a screen for an Ipad 6th gen. The screen wasn’t original but i transferred the original home button with touch id. The home button works, and the iPad expects touch id, (it said unavailable with generic button), and asks me to place my thumb. However, the sensor reads nothing, and it isn’t working. My placement isn’t perfect, and i will be fixing the button to sit properly. Is there any specific reason it isn’t working? Perhaps there are some connection points which aren’t touching due to non-proper positioning?
