What's the first thing you think about when buying a new device? For me, it's usually something along the lines of hoping the device lives up to the idea I've had of it in my head for the last few weeks or months. For many it's the hope that the phone lasts a long time, or at least as long as they need it to, whether that be 8 months or two years. In fact, the absolute last thing that anybody wants is for the phone to function improperly. Most manufacturers, Samsung included, go to some pretty great lengths to prevent anything from going wrong with the device once you unbox it and power it on.
When it comes to flagship devices, OEMs probably take especially great care in covering every single angle they can when it comes to potential issues. Samsung did this with their Galaxy S5, because they certainly wouldn't want their most anticipated device of the year to have a ton of malfunction problems. Samsung's testing facility in South Korea is actually pretty amazing, with all kinds of equipment to test the Galaxy S5 in a range of different settings with many different factors. The tests propose just about any sort of scenario or problem one could think of, from drop tests to determine the phones ability to withstand the fall, to camera and audio tests, to repeated depression of the home button to make sure it won't break down. We could imagine the home button test consists of pressing the button literally thousands and thousands of times just to be safe, and it's actually pressed until it breaks so Samsung knows just how long that will be.
Samsung even has a crazy looking room(it actually looks like something out of a science fiction film)lined entirely in foam to test out the phones radios. The room with all the blue pyramid shaped foam pieces on the walls, floor and ceiling you see below is designed to mimic a wide open environment. The foam actually absorbs the waves to complete this test. They have an elaborate setup to test how the phones radiation output can affect other electronic devices inside our homes, and they even have a setup where they can test how much radiation gets absorbed up into the human body with a special fluid that is supposed to mimic human bodily fluids. Since the new Galaxy S5 is dust resistant, you probably could have guessed that they have a small chamber set up to test how dust resistant the Galaxy S5 actually is. Well, they do have that and of course it coats the phone in dust to see if any of it gets inside the device. They test the camera in a number of different ways too, like the range of the flash, and lighting tests. They also test the phone for heat output. Basically, they test everything. Anything you can think of, Samsung has probably tested it. We may not notice it, but OEMs do much more than we know to ensure the phones work as intended.
