iPhone XS Touch Functionality Lost After LCD Screen Replacement

Hello all,

My apologies if this question has been beaten to death, but my searches of the forums didn’t turn up any helpful results.

I am replacing the screen on an iPhone XS. I am going from an OLED original screen to an iFixIt LCD replacement screen. I installed the new screen without any hiccups in the process and powered on. Everything looks fine, I just don’t have any touch functionality. To troubleshoot, I removed the new screen and put the old screen back in to test. The old screen does still have touch screen functionality and works correctly. I reinstalled the new screen and again lost touch functionality.

Do I have a faulty screen replacement? Nothing was damaged that I can see in the installation process and considering I was able to install the old screen without any damage, I’m guessing human error isn’t to blame - although it certainly could be. Any help/advice would be greatly appreciated!

TIA
