What was difficult with this protector was that the surface that sticks onto the phone screen is super sticky and if you get a dry finger, even slightly attached to any part of the protector that isn't wet with applicator fluid then you are going to get a slight or huge finger mark on the protector that you cant remove at all, which is what happened to me. so the screen has a hazy triangle mark about 4mm x 4mm x 4mm. Once the screen is on you can't see it at all and the images are still clear.
The screen protector was left on to cure for 4 days (Truly stuck on.) as the phone was an upgrade and needed a nano sim, which I didn't have at the time.
If you intend to use this screen protector without a phone case then I believe that it will protect it from light scratches no problem. The feel of the protector on the screen is good, your fingers glide and there's hardly any drag, the responsiveness of the screen is not altered either.
There's a very slight haze that is visible when the screen is off.
The protector fits edge to edge with about 0.75mm gap all the way around the edges apart from the camera cut outs.
So I purchased a Galaxy S8 Case Crystal Hybrid Glitter-Rose Quartz case to pair with this lovely phone. To my surprise, unfortunately they are not compatible even from the same manufacturer, who'd have thought it.
So now all for corners are catching with where the case sits on the screen and the protector has come away from the screen on each of the long edges about 1.5cm long.
So if you intend to use a case with this screen protector it needs to be a case that overlaps the screen by at 2.0mm all the way around the edges in my opinion.
As always MobileFuns' service was impeccable and purchase went fine as did the delivery of the item, plus I had a £5 off voucher for my birthday sent via email.
I hope you found the information contained in my review helpful.
