I bought three of these tempered glass sheets for the iPhone 6, one for a white one for one black and one spare. The 0.3mm thickness is still ok, you realize the glass, but it does not bother. The touch surface works well. When white iPhone you see no deterioration, but unfortunately very much the blacks! Here around is a narrow margin below the glass to see, like a bubble. This border can not be removed with more pressure, or by swiping. I have tried several times and two of these films dirty!
