The stores claim that this specific tempered glass is for the A8, while in reality it is for the A7. Practically, this means that it does not cover the entire screen from edge to edge and the gap for the camera is not in the correct position (it barely covers the lens). Furthermore, it significantly reduces the touch sensitivity compared to the same screen without this specific tempered glass. The cleaning cloths that come with it will be 90% dry (as they were for me, as well as for other tempered glasses). With a little bit of clean alcohol on a tissue, the screen can be cleaned perfectly fine.
