this is the package looks like:



WHAT PROBLEM DO I HAVE:: I dont know but LG G3 D855 International (EU) arrive with a glass screen protector applied in it...so, i dont know and i buy this on the picture above!! For apply that i need to remove the one in my G3 (who i'm thinking is plastic), when come off i see is a glass protector but remove it anyway...and for test i have broken it for my mistake (very bored with it)!

happy to have a new one when i'm applying it see dont fit on my screen, have almost 2mm in both sides with dont be covered by this screen protector, in top and bottom is about 1mm nothing special but in sides is way worst!

I know is a cheaper screen protector but, i ask: anyone already have the same issue with glass screens protector?

sugestions for a better than fits well?

thanks
