Bought before going on holiday, I tested twice at home, immersed for 2 hours with dry tissues on the inside and no problem. I put my camera and plunged into the sea and the pool several times without any problems. It was possible to take pictures with my camera because it is small and so it goes on for size at the transparent window. As against a Samsung Galaxy S4 comes in hair cell but do not allow taking pictures (hidden objective by the blue plastic part). Using a touch screen is a bit slower to use but quite adequate. The picture and sound is really perfect as if he had nothing ny around the camera! By the Case against really does not float, so keep it well in hand! I recommend fully!
