iPhone 6S Finger Sensor not working after screen replacement
Hi, i have 3 iPhone 6S LCD screens, 2 of them the LCD and touch are good, home button also good (can return to home page), but the fingerprint sensor not working. Only 1 LCD screen everything is fine (all working, including home button and finger sensor).
Anyone knows what happened to that 2 iPhone 6S LCD ? Is the finger sensor related to the LCD screen ? I just can not understand why the home button works but finger senor not working. Thanks !
Es esta una buena pregunta?

Chances are that the home button extension cable which comes together with the iPhone 6s screen is faulty. You carefully transferred the home button itself carefully right?

Hi, thanks for your comment ! Yes, i know the home button extension cable comes together with the LCD screen. And I tested, the home button works perfectly, it can return to home page. The problem is the fingerprint sensor is not working, very strange. I have 3 iPhone 6S LCD Screens, only 1 LCD home button working and fingerprint sensor also working, only another 2 LCD the fingerprint sensor not working (but home button works - can return to home page)

Hi, I am a technician of eddogo company, I have repaired experience of this problem, I replace the screen(no replace the home button flex cable), and then home button work but fingerprint sensor not working. I try many ways to solve the problem, at last, I found it is the Motherboard Antenna Flex problem, but 6S motherboard antenna flex no easy to replacement, I recommend replace the backlight to try it again

hi, Thank you all for comments ! After I had a deep investigation, i found the fingerprint sensor is actually related with the screen. I tested 10pcs iPhone 6S LCD Screen, 7pcs everything is fine (home button can return to home page and fingerprint sensor is also good), 3pcs the home button can return to home page, but the fingerprint senor is not working.

So, i got a conclusion - if you bought a new 6S LCD Screen, and tested everything is fine but only fingerprint not working, then you have to return it to your supplier. Your supplier can fix the problem by replacing the backlight. The backlight is 3D metal plate, just change it, the screen will be fine.
