I replaced my iPhone 6s Screen and Battery. I replaced the screen and everything worked fine. I then replaced the battery with one from another donor iPhone 6s and Touch ID disabled, and the speaker stopped working. I tried factory resetting the phone, disconnecting and reconnecting the components I replaced, putting the originals back in (home button, screen and battery) Still nothing. All help would be hugely appreciated. Thank you!
Hi I have had this issues with other iPhones and iPod touch and I found that if you carefully clean the connectors with a cotton bud and as high percentage IPA you can get it can remove debris that our eyes can’t see that will usually cause the issue Hopefully this will help you Thanks:)
