But White Dome is too costly, and just imagine that you are dropping the mobile just after a week of applying it and the tempered glass breaks. It is really a hell of a thing to imagine. So with that price I can buy 3 or more protectors and use it for a long time.
I first applied an IQ Shield LiQuidSkin vinyl protector, which I've used on other phones. It applied perfectly, but the S Pen left little grooves in the surface. I just installed a Whitestone Dome curved glass screen protector. I bought the two-pack on Amazon for $49 (a $10 off sale), so I'll install the second one on my daughter's Note 9.
The price seems high, but when you see the install kit that comes with it, including an install frame for perfect alignment and a UV light to cure the adhesive, it makes sense. $25 to protect a screen that probably costs $250 or more to replace seems like good insurance to me (I don't buy phone insurance, as I consider it too costly up front and when used with the deductible). If the phone ever falls and the screen protector cracks but saves the phone glass, I will be ecstatic that the impact was absorbed at the cost of a mere 25 bucks.
I read reviews on many glass protectors, and most were decidedly mixed. Reviews on the Whitestone Dome seemed the best. I like that there are no black edges at the top and the bottom, and the curves of the glass are only on the sides, not the top or bottom.
It works perfectly with my Spigen Liquid Crystal clear case, which comes close to but doesn't tough the glass protector at all (so the case can't pry up the screen protector). There is a very slight gap at the top, bottom and sides between the case and the screen protector (about fingernail thickness), but I don't think anything could impact the phone directly (without hitting the screen protector).
The application process went very smoothly, though it is multi-step and somewhat complicated. I recommend watching the install video a few times, and also reading the instructions carefully, to really get the sequence of steps down in your mind. Also, make sure that the table you use is perfectly level.
It went on perfectly aligned, the fit is great, no dust or bubbles. Touch functions seemed to work fine on the default setting, but I went ahead and turned on increased touch sensitivity.
Of course, it's too early for me to say how well it will remain adhered to the phone with use. But I think the fact that the adhesive is UV-cured, plus the case pretty much protects against anything prying up the edge of the glass, should give good long-term results.
No more grooves from the S Pen, a perfectly fitting and clear case with smoother feel, and hopefully better protection if there ever is a drop (I am being so careful and conscious of deliberate and firm handling of this phone!). I am very pleased so far.
