when applying screen protectors i always run then shower on hot tobhet the bathroom bit steamy and then apply it, using a card to push out bubbles. the steam keeps dust particles out of the air.
I took a steaming hot shower, then soon as I finished I grabbed my switch, wiped off the screen and applied it while in the bathroom. The steam keeps dust down. Applied it first try with no bubbles.
if u dont have kids, u dont even need to use one...waste of money imo...only use "shirt, towel etc" to wipe the screen off, dont ever use paper towels or kleenex cause the wood that is in them will scratch the screen...same goes for phones
This is why I'm against Screen Protectors it's any eye sore and u won't fully experiencing the screen for what is, unless you have kids I say get rid of it
