Before the screen replacement everything worked. After i replaced the screen when i turn on the phone the apple logo boot loops a couple times before it goes to the home screen (10-15mins). Also a error comes up saying home button needs service and assistive touch appears. Home button scans my finger(touch id) but doesn’t work or vibrate when i click it. Also the rest of the phone doesn’t vibrate (side switch and vibrate on ring)….. I have done a force restart and restored it on DFU mode in itunes I did have the vibrate and home button working at one point but then randomly stopped. I unscrewed the home button screws slightly and it was working then suddenly stopped when screen was put on.
If the old screen still works try the home button on that one. Either the replacement screen has a faulty home button connector or the home button got damaged when transferring it to the replacement screen. If the home button is really faulty you’ll have to get the screen replaced at apple (put the old screen back on before getting it done).
