Hey guys. Just fixed a Iphone 7 screen. Normal process of moving over the front camera flex, speaker, lcd heat shield, and home button. Well when I finished it and pressed the home button it starts vibrating rapidly and opens recent apps. Nothing looks torn or bent so I dont know whats wrong. Any suggestions?
I’d check the Taptic Engine to make sure it is secure and make sure everything is grounded properly. Also, go into the Touch ID settings to see if that has any impact. Good luck!
Hello, i faced this trouble twice in a week with two different iphone7 with very badly damaged screen (and one with water damaged). They have been previously opened so i don t know if i did the mistake at least for one but for the water damaged the trouble was already present: the flex cable from the button (not from the touch id) is cut near the grounding pad
as a capacitive sensor the button sensor is driven using specific pulse to sense the capacity change due to finger: with the track cut… it sense using the second half of flex board. Most of such circuit have a automatic calibration mode and without real sensor area, the button become crazzy. I will try two have my button repair in microsoldering surgery…
I had the same issue with an iPhone 7 on which was doing a back case swap. The original phone was badly damaged and the case was bent. I had ordered a new back case and swapped the motherboard and other parts. The touch ID works , but the home button would sometimes multiple-click. After trying different screens, swapping the taptic engine, I put the home button under the scope and found the slightest wear/tear on the cable where it folds in half. I’m guessing that’s what is affecting it.
Do you have another screen assembly to test with? It could be a faulty screen. I would also go back and reseat any connectors, and make sure the screws holding in the home button are not overtightened.
Same problem here and I’m on my 3rd screen. After 1st screen, home button worked just fine but phone would randomly turn off usually while taking portrait photos but sometimes other times too. 2nd screen, home button stopped working but Touch ID was working fine. 3rd screen, rapid clicking but home button worked and Touch ID still worked. iPhone 7 Plus. I’m at a loss. No damage to any cables or connectors.
the u10 chip has been damaged remove the cable with heat
This is an issue with the haptic engine. Anything from minor bending or an unsecured connection and cause improper communication from the home button, to the haptic engine. If all is secured and well. You will need to replace the haptic engine. I have had to complete this repair several times. Fairly simple and a kit with tools can be obtained from amazon for about $25.00 There are severa turorials on YouTube for this repair.
My home button if clicking by its self is so annoying!!
iPhone 7 home key flex has been broken while changing screen, go to any professional shop it is easy to repair this problem as only a small secondary flex in home key damaged not primary big flex.
U hv broken touch id small flex u hv to make 3 jumper now
This happened to me. I opened the phone again, removed and repositioned/reinstalled the same button. Tinkered a little bit with the screws’ tightness, and problem seemed to disappear. But I’m guessing some home button spares are just not the best anyway.
