I have the same issue with my 16 pro. Already wasted 3 spigen protectors and 1 vivid. Now I'm waiting to try again the replacement set of 2 of the spigen seller, in case the previous were just faulty products. I see good reviews for spigen glass from many 16pro users. I didn't expect to be such a pain in the @@@ to fit a simple screen protector, especially with a guide installer tool! What a waste of money! It is the first time to consider not using a protector at all!
