When I opened up my iPhone 7 to fix my battery, I may have pushed the spudger too far. I successfully installed my battery and the phone turns on fine, but the home button stopped working along with touch ID. How do I know i need to repair the home button vs fixing what I may have broke when opening up the phone?
Is this a good question?

The iPhone 7/8 series have a very inconvenient bend on the Home Button flex. It’s really easy to tear the flex, either near the logic board connector or at the 90 degree bend before it sneaks underneath the LCD heat shield. You have to be careful when you lift the screen off the first time but also anytime the flexes are connected and you have the device open.
The other area that is easily damaged is the connector on the Home Button itself and the opposite connector on the short flex that runs underneath the heat shield.
The long and short of it is that there are multiple failure points. You will need to carefully inspect the Home Button and flex to see if there is any damage. Magnification here will help. Look for tears to the flex or any physical signs of damage. You should also check the connector to insure none of the pins are damage or that there isn’t any debris.
Unfortunately, there is no real DIY way to fix a Home Button, only Apple can replace it if Touch ID is required. There are now some aftermarket Home Buttons that allow “click to enter” so you could look at those (or AssistiveTouch in the Settings as a software workaround).

Is the flex the cable that runs with 2 others from the top of the screen from screen to case? Thanks so much for your answer! Really helpful
