| + | * The cable which carries the Touch ID signal from the display to the logic board is commonly torn. It is the outermost cable connected to the display and susceptible to damage if tools are used improperly. Use a functional display to test if this is the issue. If this restores function, replacing the display is recommended. |
| * Check for tears in the flex cables attached to the home button itself. They appear most often in corners and can be difficult to spot with the naked eye. If your cable is torn, and Touch ID is a necessity to you, seek repair from Apple. Repairing the home button cable to restore Touch ID is feasible, but requires running tiny jumper wires. Even many seasoned microsolderers avoid these repairs. | |
