There is yet another issue that is starting to be more common among the iPhone 6 and 6S variety phones. The home button no longer registers a click, but the touch ID still works.

Symptoms may include:

  • Only registers click occasionally.
  • Only works when the home button bracket is not attached to the LCD.
  • Only works if the button is held or twisted a certain way.
  • Will not register click at all.

3U tools should still be able to recognize the home button, and Touch ID should still work. If they do not, this guide will not fix those problems.

  1. Remove the two 1.9 mm Phillips screws securing the home button bracket.

  3. Use the pointed tip of a spudger to disconnect the home button cable from its connector on the display assembly. Use the pointed tip of a spudger to disconnect the home button cable from its connector on the display assembly.
    • Use the pointed tip of a spudger to disconnect the home button cable from its connector on the display assembly.

  4. The rubber gasket surrounding the home button is very thin and tears easily. Apply mild heat (with an iOpener, heat gun, or hair dryer) to soften the adhesive securing the home button gasket.

    • Apply mild heat (with an iOpener, heat gun, or hair dryer) to soften the adhesive securing the home button gasket.

    • Using your fingertip, gently press up on the home button from the front side of the display assembly. Use firm, constant pressure to slowly separate the home button's rubber gasket from the front panel.

  10. Test continuity between top part of the resistor and the home button.
    • Test continuity between top part of the resistor and the home button.

    • If you get constant continuity between these two points, you have another issue and this process will not fix your issue.

  11. Now that you have confirmed the issue, you can fix it by running an external trace between the two components you just tested.
    • Now that you have confirmed the issue, you can fix it by running an external trace between the two components you just tested.

    • Solder your wire to the physical part of the home button first.

  12. Guide the wire to the second component It is easier to keep the wire in place if you cut part of the glue out in a line. That way you can insert the wire into the cutout to prevent it from moving Add some glue or UV resin to keep the wire in place.

    • Solder the wire to the top end of the component.

  13. Add some UV Curing Glue to the solder points.
    • Add some UV Curing Glue to the solder points.

    • To be safe, you can place some Kapton tape over the top of the new trace to keep it from moving. Be careful as this new trace is fragile where it isn't glued.

    • Follow steps 1-6 in reverse order to re-assemble the device.

Conclusión

After testing the home button and confirming that the repair worked, you can re-assemble your device.

Superb it worked

Looks like have to attempt this. Have done fairly fine soldering before but maybe nothing this small. What size jumper to use? 0.1mm or 0.02mm?

Great tutorial. There is a diagram floating around on the web that has the polarity reversed. I did that first and didn’t work before finding this guide and corrected the wiring. Works great now.

Besides a good fine tip soldering iron and at least magnifying goggles, really good flux makes all the difference on this job since everything is so small. I had some clear liquidy flux (Kester 951? don’t recall, bought long ago to help reflow GPU+SOC BGAs) That worked great as heat instantly flowed to all the right places. Necessary with tiny solder points and rework wire.
