iPhone 6S Plus Finger Sensor not working after screen replacement
Now yes I understand this is a common question but there are still a lot of questions regarding this matter and contradicting answers. I have a few questions below...
I have been reading this post here: BTW
Now he replaced the screen using the original home button from the device which is what your supposed to do in order to keep touch ID working. He claims that the home button still works and that touch ID doesn't work on only 1 of the replacement displays he has. I have the same scenario, the touch works but the touch ID does not.
Also a user mentioned electrical damage could have been a cause if the battery was not disconnected during disassembly. I had it disconnected I believe but is there a way to test that out?
Now when the device starts up you get a popup saying "No Touch ID". Is that what is supposed to happen when touch ID does not work or is this a different problem? I couldn't tell because some people don't have that popup and touch ID just doesn't work.
Now some people say the back light / flex cable could be the problem but how do I know that for sure?
Please help. I am experienced around taking apart apple devices so I doubt I damaged a part in the process. Thanks,
Also unlike other devices I have worked on this one has experienced lag at some points after the replacement. Could that mean a defective digitizer?
Questa è una buona domanda?
