I finally found a glass screen protector that works! I've tried a soft one from Ringke, an inexpensive curved glass one, the $35 glass from Gobukee and finally the $50 glass from Whitestone. Obviously, the Whitestone is the keeper. The Ringke smudged more than any other protector I've ever tried. The curved glass had a black adhesive ring at the edge and killed the sensitivity. The Gobukee had potential, but after watching the installation video and trying twice, I couldn't remove all the air bubbles and neither can others. Now for Whitestone. I really hesitated due to the price. I'm not wealthy. But after reading a review that said "$50 isn't that much when you're protecting a $900 phone". It is worth every penny. The expense comes from the included UV curing light and all the parts you use to properly install the glass. I have never seen a protector with so many parts, stickers, cloths etc. I strongly suggest that you watch the installation video once or twice. Make sure you're in a dust free room. A bathroom after steaming is suggested, but I don't have enough counter space to be comfortable spreading out the parts. Also read the directions! This is the most involved installation than any other protector. Not difficult, just many steps; and they work. It took me about 30 minutes and it works perfectly. No decrease in sensitivity, no interference with my Ringke case, it's great! They even give you instructions and additional adhesive if you don't get it right the first time. When completed, keep everything. If it ever cracks, you can get replacement glass for a lot less. (At least that's what they say) Unfortunately, I don't own stock in the company and I get no kickbacks for any sales. I paid full price for mine.
