\u003Cp\u003E\u003Cspan\u003EBefore any new device in the Galaxy series is launched, numerous tests are conducted to ensure its capability to withstand the wear and tear of daily life. New features undergo rigorous trials to meet specifications, while the device is placed under extreme conditions to determine its durability. From heat tests to drop tests, it is Samsung’s aim to protect devices even from the previously unexpected.\u003C\/span\u003E\u003C\/p\u003E\n\u003Cp\u003E\u003Cspan\u003ETo discover more about what each device must sustain during these trials, the Newsroom paid a visit to the Reliability Test Group at Samsung’s Digital City in Suwon, South Korea. \u003C\/span\u003E\u003C\/p\u003E\n\u003Ch3\u003E\u003Cspan style=\"color: #000080;\"\u003E\u003Cstrong\u003ETests at Every Step of the Way\u003C\/strong\u003E\u003C\/span\u003E\u003C\/h3\u003E\n\u003Cp\u003E\u003Cspan\u003EThe Reliability Test Group is responsible for testing mobile and wearable products sent from Samsung’s manufacturing sites in Suwon and Gumi, South Korea,\u003C\/span\u003E \u003Cspan\u003Eincluding the Galaxy S and Galaxy Note series of smartphones.\u003C\/span\u003E\u003C\/p\u003E\n\u003Cp\u003E\u003Cspan\u003EAs soon as decisions begin to be made about a new device or model, the Reliability Test Group gets to work. Once the specs and features are determined, the group considers which parts require testing and verification, and the process starts even before the features have been fully integrated. Test results are immediately passed on to the development division for improvement. Throughout development, the test group engages continuously in the production process, processing feedback about the device even after its launch and release. More than a dozen tests are required to validate a product. While the number varies from device to device, thousands of models are put to the test before launch. The tests are designed to evaluate how the devices perform during normal day-to-day use and follow a standard based on internationally-certified test criteria.\u003C\/span\u003E\u003C\/p\u003E\n\u003Ch3\u003E\u003Cspan style=\"color: #000080;\"\u003E\u003Cstrong\u003E1.

There is also an artificial sunlight system which can simulate different lighting conditions, from a dark night to a bright day. Testing in an indoor lab ensures that the light source is unaffected by external factors, leading to more accurate comparisons. Tests are also performed outside of the lab in real outdoor environments.\u003C\/span\u003E\u003C\/p\u003E\n\u003Ch3\u003E\u003Cspan style=\"color: #000080;\"\u003E\u003Cstrong\u003E2.
