This isn’t the screen. It’s the midframe.
I’ve never gotten this rubber piece on without it ripping . I’ve never had a problem with the operation of the phone upon reassembly. I wouldn’t worry about it.
In the second and third pictures, the screen is cracked quite a bit. In the first picture there are no cracks. You must have done that taking it apart. Is it that difficult to take apart without breaking the screen? If so, the difficulty should be changed from Moderate to Difficult!
I’ve given up using a plastic spudger to try to open any of these phones. I use a metal one with a flat base and a very sharp end…close to a razor. As long as I’m careful, it won’t slip and scratch the base. It’s much easier than using these plastic spudgers.
I broke one. It just would not go back around the part, so I just put it around what I could and the phone worked fine. I’m replacing the panel on another one right now that someone else had already replaced, (the girl broke her screen again) and the little black part was just laid on top of the silver part and it worked fine. Don’t have a clue why that little black rectangle is even there. It doesn’t appear to be needed.
I know your comment was posted a long time ago but just in case someone else has the same problem, the only difference in the screws are the lengths. The ends are the same.
If all you need to do is replace the speaker, then this should be your last step.
I don't see it either. I think the metal clip is on the model A1332. The GSM model.
As Sam Lionheart states at the end of this guide, some of these phones have an additional antenna on the opposite side of the phone. Be sure to detach it before removing the motherboard.
I had the same thing happen just now. I was working on a G900A. A real PITA!
