7+ home button unresponsive but causes phone to freeze when touched

I attempted to repair a iPhone 7 plus after previously fixing a iPhone 7 with no issues.

When the repair was done it said Touch ID not working but the phone would freeze for a minute when the home button was touched. When the home button is touched no vibrations or anything.,

I also tried a different LCD and also the original screen but it still has this issue. I also tried a iPhone 7 home button knowing the touch ID wouldn't work but I wanted to see if the vibrations would allow it to at least function with out the touch ID.

I took the necessary precautions i.e; disconnecting battery, not hitting metal on metal, didn't rip any cables.

I've done multiple resets; holding power/volume down button.. nothing works

Any advice would be greatly appreciated.
