Hi.
I often find that the home button for the ipad 5 needs to be replaced because the click mechanic does not work after being transferred to a new screen. The button does not appear to be damaged and the click mechanic does work if I press on it with a spudger, however once I place the bracket in place it will not click, or only slightly. If I replace with an aftermarket, everything works and the click is solid.
Note I have repaired multiple tablets so I have some idea what I doing but I cannot figure out why this happens unless its a fault with the button.
