Replaced screen doesn't turn off when I hold it to my face for a call
I got a new iPhone 7 LCD Screen and Digitizer Full Assembly today. After I replaced the new screen, everything looks good. But when I answered a phone call and held the iPhone to my face, the screen did not turn off.
I put back my old cracked screen and that one does turn off when I answered a phone call.
Any idea for this issue? Or I should return it to IFIXIT?
