Released in early 2015, the Samsung Galaxy S6 marked a dramatic design pivot for the Galaxy S series, ditching the removable plastic backs of earlier generations in favor of a dual-glass chassis reinforced with an aluminum midframe. It introduced a sharp 5.1-inch Quad HD Super AMOLED display powered by the 14 nm Exynos 7420 Octa chipset and 3GB of RAM. The 16 MP main camera featured optical image stabilization (OIS) and an f/1.9 aperture, establishing strong camera performance for its era. Launching with Android 5.0.2 Lollipop beneath Samsung's TouchWiz UI, the device was officially supported through Android 7.0 Nougat. The aesthetic transition to a sealed glass-and-metal architecture introduced significant trade-offs for hardware longevity and serviceability. Unlike predecessor models that offered instant battery access via a snap-off back cover, the Galaxy S6 glued the rear glass panel directly to the frame and buried its modest 2550 mAh battery beneath an internal midframe core. Accessing internal components requires precise application of heat to soften tough perimeter adhesive, delicate prying technique to avoid cracking the rear glass, and unbolting the midframe before reaching the battery, display connectors, or logic board. Over long-term use, several common failure patterns emerge on the Galaxy S6. The primary hardware bottleneck today is battery degradation; the original 2550 mAh cell frequently exhibits poor charge retention, severe voltage drops under load, or chemical swelling that pushes against the rear glass. The Super AMOLED display is prone to burn-in or stress fractures from drops, often requiring full panel assemblies to resolve image loss or touch unresponsiveness. Additionally, the micro-USB charging port can experience physical pin wear over repeated plugging cycles, and the physical home button assembly or side switches can lose tactile responsiveness over time.
