Home button tap isnt working but touch ID is
I have two iPhone 7 plus's one Was working completely fine Until I decided to test out the screen on the broken one that Is waiting for parts. So the broken one needs a new screen and a battery I replaced the battery and figured well lets test it out with my phone that's currently working so I took of the screen and attached it to the other and everything turned on and worked except the home button the touch it and the ID witch I was expecting but when I put it back on the original phone only the touch ID works and not the home touch its self I have to use the assist and also now the volume will not go up or down with the buttons it registers me trying to turn it up and down but doesn't do anything. I tried a hard reset a factory reset and I am just all out of ideas !
Is dit een goede vraag?
