There are some feedback of Galaxy Samsung S8/S8 plus 3D glass protector produced by some manufactures.
A :S8/S8 Plus screen is very smooth , it is polished much more for this latest. If with normal glue on screen will slide when touch it .
B: There will be glue residue when install case-friendly 3D glass especially for transparent .
C: lots of S8/S8 3D full glass protectors’ edge is not flat, it is because some manufactures are less of experience for such curved glass structure as well as the way to make the process improved.
As upgrade of the technology , the 3D curved glass will make the best.
