In general practice

The bag is very a handy gadget and for the price you can not complain really. I want to reveal just my experience here:
After repeated testing with cellulose cloth and using cell phone in the bath, I was sure that keeps me close the bag. In Tropical Iceland they came for prolonged use. Unfortunately does not work for physical reasons the touch panel, it is this probably depends on what on the phone display reacts (pressure / heat sensor / elec. Pulses etc.). On my HTC OneX the reason is simple: under water, the film of the bag is pressed on the entire display, so it perceives no more finger pressure. If you try the automatic trigger, ie trigger afloat underwater photography, works of, unfortunately, not because it breaks with the immersion. But as long as you hold the camera underwater and operated partly afloat the display folds it quite well. If you try to take pictures with flash, which is, unfortunately, nothing, because the flash is reflected in the film and you get a white image. That's a pity, because come in the dark or at dusk without flash only krisselige and blurred images materialize. So if you expect it to take pictures under water and thereby would have razor-sharp images, which I rate equal to either buy an underwater camera or maybe there is a cell phone pocket that creates the. So I have to say I had great fun to be able to take my phone in water. I could make a lot of photos that I would not otherwise have to make. Functionally, the bag is great, even from the point that I can take my phone now with on / in the bath, have to have it fall into the water and becoming damaged without fear.
