The trick to perfect screen protector pasting?
Dont ever use the wipe cloth that usually comes with the screen protector. The more you wipe it on your new screen, the more dust particles you get.
Just remove the original off-factory screen protector, (dont blow the screen please), and paste your own screen protector instantly! Do it in a clean, closed room.
P/s: yay, finally installed wordpress on my mobile! Mobile does replace PC, dont you think?
