It's actually not that hard or complicated to do a perfect job. First of all don't expect it to be 100% perfect the first time you apply it. Here's what I do:
1. Get your tools ready: a microfiber cloth (2 if you have them), a can of air, some scotch tape, and some large adhesive tape (the 1x2 USPS priority mail labels are perfect).
2. Use the mf cloth to wipe dust off the screen, then lay the phone down on it. Use the can of air to blow remaining dust off the screen (don't worry if it's not perfect, it almost never is).
3. Apply the protector and focus ONLY on alignment (don't worry about bubbles or dust).
4. Once it's aligned perfectly the way you want. apply one or two scotch tape pieces on one end (the top or bottom end, not the sides). These are going to be your pull handles. What you want to do now is pull up on one end and use the USPS label to get all the dust and other stuff off of the inside of the screen protector (don't pull all the way up, only up to the middle). Remember the primary reason why you have bubbles is because you have some piece of debris in there.
5. Using the USPS label you should be able to do half the protector in just a couple of tries. Once done, pull the scotch tape off and create your handles for the other end, repeat step 4, done, no stress or other hocus pocus needed.
