getting screen protector to not be bubbley?

Depending on how big/where the bubbles are, you can usually squeeze them out by rubbing your finger over them and pushing them to one side of the phone. If you have bubbles because there is some lint underneath the protector, grab some tape and lift up the protector and use the tape to peel off the dust/debris on it. Works everytime for me.

 

I've always used a small amount of water and some washing up liquid to apply my screen protectors.
It makes it easier to remove bubbles and to get the screen protector into place without touching the sticky side.

Once you have it on wrap a credit card in a lint free cloth and use it to pull across the screen to remove the bubbles that remain.
I've had no problem with this method just make sure you never push the excess water towards the ports on the phone and mop up the excess with a cloth.
