How To Get Bubbles Out Of Your Phone’s Screen Protector – SlashGear

Generally speaking, a screen protector bubble arises from a spatial cavity between the surface of your phone and the sticky side of the protector. The protector is supposed to be flush against the screen, but if something gets in the way, a little pocket of air forms and bubbles up in the sealed space. You know how when you pull an overturned canoe underwater, you can stick your head up into it to breathe? It’s kind of like that.

So what can cause this cavity to form? The most common culprit is a spot of dust on your screen. Even if it’s small, as long as it interferes with the stickiness of the protector, a bubble can form. Bubbles can also form if you apply the protector improperly, just sticking it right to the screen rather than rolling it downward from the top.
