Hi i was replacing my iphone 8 plus screen when i was transfering the home button and once i fit it in and put the screws in and i put my screen against a bright lamp i noticed some gaps. then i removed the screws and i took the home button out and put it back in many times but the gap wouldnt go away is this a screen problem? thanks.

Yes, it’s very likely it’s a lower quality aftermarket screen, some of them are known to show such imperfections.
