super slow boot touch id not working
Issue:
Takes 5 mins or longer to boot after boot touch ID/ home button not working. Sometimes it will boot up in normal speed also with a working touch ID/home button
Background:
Customer replace the screen them self and they say before screen replacement everything is working.
Troubleshoot:
I have try with everything disconnect , Only with LCD/battery/Power problem persists.
physically phone is little bend around sim slot area and i have check with microscope to see if there's any component that fall off.
during the super slow boot apple logo will blink 2-3 times
Questions:
i know is the logic board and ic chip issue mostly likely i will just need to reheat the chip. which ic chip can cause the phone to boot up super slow and also have interference with Touch ic/home button.
Es esta una buena pregunta?

So the phone was working fine for a few hours . I was able to recreate the problem when i try to connecting and disconnecting the home button and boot. What bothers me is that lets say the home button is damage the phone should still boot normally without the button connected but phone boot up super slow 3-5 mins

@linxg The problem could be the home button. I have 2 iphone 7 here, when the start without button takes minutes to turn on. Then they work well once started.

any of you familiar with u10 ic on home button Could that cause any problem with the slow boot and not reading home button/ touch id .

it could be a shot somewhere on the logic board. If you have a microscope I advise to check all connectors for missing or damaged parts. Could also be that two pins are shorted and what you experience might not be a slow booting, but multiple reboots during the startup ?
