Raise the humidity to apply thin film screen protectors without bubbles.

If given a choice, I will always opt for a matte screen over a shiny screen – I dislike screen glare, and I especially hate the way modern screens collect fingerprints. They’re easy to wipe off, sure, but they still accumulate until you do. As a result, I will usually put a matte thin film screen protector on my devices. I’m very fond of the iCarez protectors – they’re cheap and high quality. Applying these comes with a massive annoyance – bubbles under the film. Moving too fast and not smoothing as you go can cause raised areas, but those are fairly easy to eliminate by being careful and pressing a card down from the center to press the bubble to the edge where it can escape. Much more insidious are the bubbles caused by pieces of airborne dust that stick to the screen – if one of those gets trapped under the screen, it can be very difficult to fix. Some screen protectors include little stickers that be used to pull dust bits off of the film, but I haven’t found them to work very well. The best way to deal with these is to prevent them from happening in the first place, and the best way to do that is to reduce the amount of dust in the air and the amount of static on the film that draws the dust to it. Barring a cleanroom environment which you probably don’t have available to you, a good trick here is to apply the film in the bathroom. Close the windows, run the shower on hot for a few minutes to raise the humidity in the room, turn it off and wait a few more minutes for the dust to settle, and then go in and apply the film. Don’t forget to cover the floor with a rug or towel if you need to – bathroom floors are usually very hard and you don’t want to accidentally smash your phone or tablet on the tile when you’re doing this. This method isn’t completely perfect, but it will substantially cut down on dust problems and make this a great deal easier.

That’s it. Good luck!
