Hey! I know exactly what you are talking about! It took awhile for us to be able to do our Samsung screens and that is due the the very issue you are talking about.
We finally found the perfect screen that addresses the issue of the curved glass not sticking. Our screens use a UV glue process in order to make sure the screen perfectly adheres. I currently do not have our samsung process video ready. Here is a video of someone else using the same process.
If you do order one and it does not work out, I will definitely replace it so we can make it work! I have many friends with my UV Screens installed and they stick very well once they are installed.
I appreciate the question.
