Home Button and Touch I.D
I work at a cell phone repair shop and we have all been in the business for a while. So you know what were working with we use all OEM lcds not just the typical "A" grade but true apple LCDs if it doesnt have the stamp we don't buy it, yes it costs more but zero issues normally. Onto my question we did an iPhone 7 battery flawlessly turned device off removed heat covers unplugged battery then lcd then front flex. screen was removed properly we've done it thousands of times before, we put the new battery in and boom home button completely docent work. I know, "well obviously dummy you broke it." well no we didn't there was no physical damage on the button or ribbon cables we've done it so many times you get a touch on how to remove these screens so we tried soft reset, system restore new battery nothing worked. lately we tried a new screen and it works. i know if the ribbon connectors on the lcd side get damaged the phone won't boot and touch id will fail but with no physical marks i was wondering if anyone experienced or had some insight on it. ill answer any question you may have just very curious technician. Thank you.
