Android Sucks, ios is better
In my experience if you have bubbles nothing is going to remove them. The best way to get rid of them is to install the protector bubble free.
I use a Windex Wipe to first clean my screen. Dry it with a dust free cloth. Then a can of compressed air to remove any dust. Then install it by peeling back only 1/4 of the protector and using a credit card, or a card like the one shown above slowly press the protector on a little at a time making sure no bubbles get formed.
In my experience, if you apply it and it has bubbles.. there is no fix. You can try getting the bubbles out with a card or cloth, but the seal has been made around the edges so no air is getting out.
If you want to use a screen protector, invest in a PowerSupport one. It is a thicker material, is applied by peeling it from the back simultaneously as you apply it to the screen and can be lifted and reapplied with a piece of scotch tape on the corner.
