I have what appears to be a persistent bubble under my iPhone 5 Bodyguardz Pure glass screen protector that just doesn't want to shift and I want to show it to folks who have had experience of air, lint or dust under their own glass protectors to get a consensus on what it is. Under magnification (I have a 12x loupe) I cannot see anything under the glass at all. No matter what angle I hold the screen at near the window, all I see are the squiggles of adhesive/air, the polarised light effects and underneath those the pixels of the display. There is no visible physical object between the Bodyguardz and the iPhone screen. Here are the two images of the bubble. The first shows the position and size relative to the home button and the second is a closeup. The other specks visible in the images are actually dust on the surface of the glass at the time of taking the photo... I fitted the screen to my iPhone5 seven days ago. I correctly cleaned the iPhone and got the Screenguardz positioned perfectly first time. It has not been lifted up as I am aware that this would damage the adhesive. There were a few areas at the edges where there were the expected air bubbles as well the area near the home button that also appeared at the time to be a visible air bubble. Within a few hours, all the edge air bubbles disappeared leaving the screen perfectly lined up with absolutely no dust or lint under the surface but the one area near the home button just wouldn't shift. I read in the FAQ that larger air bubbles could take up to five days to work their way out but I became concerned about this one because, no matter where I pressed on the glass, it wouldn't move about like a real air bubble should. In addition, despite pressure above the area, it just shrank a little then reappeared in a few seconds. It is highly visible because of the coloured polarised light effect and has not changed in size at all since the glass was applied seven days ago. Under high magnification, it appears that the glue at its edges is incomplete and has a "bald spot" in the centre. I wondered if that despite being fortunate enough to position the glass correctly first time, I had been unlucky enough to get one that had a defect. I considered that there might have been a bubble in the adhesive when this piece of glass was manufactured and that there was in fact one small spot on my glass that has no glue on it. The spot does not move about when pressed and is showing no signs of clearing after seven days. Is it lint or is it a defect?
