It's like there's no adhesive between the two surfaces

I just don't have much luck with these screen protectors for my Samsung Galaxy S7 Edge phone. This is the 3rd one I've tried and and this one has large air bubbles in three of the corners and a small one in the forth. I try to push the air out and it just pops back. It's like there's no adhesive between the two surfaces. I had a Samsung Galaxy S6 Edge Plus that they worked fine on. Photos Attached. Any advise?
