This material will not bubble at all, with dust on the screen or not. Because it is actual glass and not a thin plastic film, it is too rigid to bubble. If you happen to get dust between the surface and the protector there are 2 situations... If it is around the edges, the colored borders will actually hide the dust. If you get dust between the clear portion and the screen, you can easily lift the protector and wipe it clean. As there is no adhesive on any of the clear portions of the protector, dust will not stick. The adhesive is only behind the colored portions of the protector and is reusable, this allow you to remove and reposition the protector.
Other protectors that are 100% clear, they are completely covered with adhesive. If you happen to get dust between the screen and the protector, it is literally stuck there. Even if you were able to remove the protector, and the dust, the adhesive has been displaced by the dust, and will leave a ghosting mark on the screen.
The reason for our design, is because the biggest issue most people have with a screen protector is it is extremely difficult to install. We worked hard to make sure this is the easiest protector to install on the market.
One question some people have raised is about the colored border being visible. Since the borders are color matched, once the protector is installed, it is nearly impossible to tell that the border is colored, or that the screen protector isn't completely clear.
It also allows the possibly later do offer color change kits at a much lower price as the entire front assembly would not have to be replaced.
