Review on 📱 2-Pack KATIN Tempered Glass Screen Protector for Samsung Galaxy S7 - No-Bubble, 9H Hardness, Easy Installation by Tim Roby

This screen protector was as easy to apply as any and its contour matched the phone's specs good (cutouts for the "Home" button, speakers, microphone, front camera etc.) Included in the box is a QR code with a link to a very short YouTube video that has few comments so far, however, half of which mention that the edges and sides don't stick.I prefer to use the sticker guides (the loop method) for installation, although I attached the loop to the long edge and wonder if it would be better (YouTube video demonstrates installing it short edge first) to reduce bubbles using the short edge as the side of the loop first.It went pretty easily with just a few large bubbles, most of which flattened very easily and the last one, in the lower corner, flattened after a few minutes and with enough pressure. When the protector is sealed well it becomes almost invisible (a dark screen is just as dark as without a protector and will not obscure or reduce a bright screen). However, I quickly noticed that this protector leaves a uniform visible border around its perimeter that doesn't go away unless the screen is as dark as the stuck-on parts. That is, light reflects slightly differently from the boundary of that tread. I suspect the YouTube comments talk about this, in the sense that you don't expect to see or notice this effect when the adhesive extends to the edges of the tread. It's so even (about 2mm on each vertical edge and about 1mm at the top and bottom) that it's clearly not an installation issue, presumably a design feature rather than a defect. Maybe this will help get rid of the bubbles by only sticking "almost" to the edges of the tread? In any case, this doesn't affect the overall fit on the phone screen as it's just the edges. This is most noticeable when the screen is dark and is very faint when viewing the screen directly. Since it's so uniform it doesn't bother me (like bubbles or cracks in the glass) but it was a replacement for the old Alpha Glass screen protector that covered the screen completely and evenly without that "bezel effect" so if you that bothers then maybe this one Kathin is not your protector. I will say that the Alpha Glass S7 screen protector I used worked very, very well and saved my screen from damage on a number of occasions (in combination with the Otterbox Symmetry case) so we'll see how this Katin behaves in the long term. .
