Lost of Auto-Brightness After Screen Replacement

The new screen came with a camera installed and the only component the iFixIt instructions say you need to transfer is the Home button, which I did and the Home/Fingerprint sensor does work after putting the phone back together. Previously I was told if I lost the Auto-Brightness option I’d need to transfer data from the old screen to the new one. I did a lot of research and found the VC-V1S which is very common and seen this work very easily. You attach the larger of the two display cables from the original screen to the VC-V1S then you click “Read” and I get all the data. Then connect new display and click “Write” and then it puts the original displays data onto the new display. The “Write” however looks like it’s working but then fails to verify after. However performing the same steps but writing to the original screen on top of the original data goes through and comes back verification successful. So apparently it won’t write anything to the new screens. Where’s this chip you are talking about?

I'd guess the camera on the screen for the camera is damaged. I've personally never seen that screen with the pre-installed camera but I'd recommend transferring the original part over because it's quite easy and it sounds like that could help. it's about as difficult as changing the home button but the first time you do it then it can be a bit confusing; however I believe they have guides to help on here.
