(4 Pack) Universal Waterproof Underwater Phone Case | ProCase

It does what it says

I was warned ahead of time that the protective box on my Samsung phone would have to be removed in order to fit inside the water tight case. It definitely did! I was able to take it underwater and it functioned okay. I confess I was very cautious and only had it underwater for a few seconds at a time, not very long. The touch screen was accessible but I had to press the icon a couple of times in order to make it work. My primary intent was to take pictures underwater, and that did work but I had to use the volume down button in order to snap a photo. Also, there is air still remaining inside the pouch when sealed and you have to pull the plastic very close to the camera lens for a good photo. I'm not sure if there are instructions anywhere explaining how to remove the residual air? if there are instructions I'd love to read them.
