Just purchased my 10 a week ago. It's overall, a good phone. But I'm going to return it. When I wear my polarized sunglasses, the display on the screen almost completely disappears while I holding it upright. I'm only able to see the display when I hold it in landscape position. I tried several different polarized sunglasses and I experienced the same result. The display is perfectly fine when viewed through non-polorized glasses. My wife has an iPhone and I'm able to read her display perfectly fine through my polarized lenses. I'm also able to see my old HTC M8 through the glasses. I'm sure this is due to some sort of anti-glare feature on the screen but its a miss in my book. The display is rather difficult to see outside in general even WITHOUT sunglasses even at its brightest setting. I'm super disappointed, I waited like 6 months for this phone to come out.
