Easier than I thought!
"I've always had my screens installed at the Verizon Store. But I bought the Spigen Tough Armor case and realized that I should install the recommend protector screen to avoid case interference. This meant that I'd have to install it myself. I studied the tutorials and watched several YouTubers do it before setting out to do it. The best tip was to use a slightly steamed up bathroom to remove the dust from the air. Then I simply followed the directions and concentrated on pressing on the center of the screen protector and working outward. Some YouTubers just rubbed willy-nilly and had bubbles. When it came time to remove the alignment frame I was shocked. No bubbles. I couldn't believe my eyes. I ran the squeegee anyway from the center to the edges to ensure good contact, and that was it. Crystal clear install. I was pleased knowing that the package contained two protectors in case I messed up. But now I have a spare. If I can do it, you can too."
