ipad mini 3 - locked home button after screen replacement

Hi community,

after the glass and screen replacement (they work both well) on my ipad mini 3 LTE, i've a problem with the original home button (i've token the old home button to put it on the new glass);

The button doesn't work well; it reads my finger print to unlock with fingerprint, but it's locked as it's always pushed and is not possible to push and use it.

I've tried the calibration but without solving.

can you help me?
