Applying screen protectors to any screen is one of the most annoying and time consuming things ever. One little bit of dust or a slight misalignment can completely ruin it and leave bubbles all under the screen, making you annoyed at all the time you spent trying to make sure that doesn't happen.
A YouTube user has come up with a genius and simple trick to make sure you get that damn screen protector on properly. By simply attaching two bits of tape to the screen protector and phone, you can get it aligned up properly.
Next time I apply a screen protector I am doing this.
