[Cicatrize]

Screen protectors are very important. If you're getting bubbles, you just need more practice with it. What I use is grid style sheets of it, and cut my own to a specific size. Then, I peel it back half way, line up one end on the phone, push it to stick in the middle with my finger, then I use a mini credit card from the edge and push all the way through the center, then push out from the center to the sides. With this method, I rarely get any bubbles. Try it out.
