Sunken & stiff home button.

I replaced the front glass/digitizer on my iPad Mini 2 & have had issues with the home button. It is recessed deeper in the glass compared to the original & it is much harder to actuate. I have remedied the alignment problem by forming the metal bracket for a flush fit, but the switch is still hard to actuate. I tested the button with the front glass removed from the case & it is still stiff, so It’s not anything to do with how the assembly fits in the case. It’s stiff enough that I have to be very aware when double clicking, as it will not always work. I don’t see any way to fix this as it appears that the switch spring is internal. The switch always operates , it just takes extra force to depress it. It’s not spongy or anything. Nice firm click if pressed hard enough. I would guess about twice the force of the original switch.
