Samsung manufactures its flagship Galaxy smartphones, including the Galaxy S26, S26 Ultra, and the brand-new Z Fold 8 Ultra, at a nearly 40-year-old production facility in Gumi, South Korea, according to reporting from the location. Situated roughly 150 miles south of Seoul, the campus is dubbed Gumi Smart City and relies heavily on automated robotic arms to lift components, tighten screws, and secure packaging.
Inside Gumi Smart City: The Automated Smartphone Assembly Line
The vast, warehouse-like Gumi production plant operates with minimal human intervention for standard assembly tasks, according to on-the-ground observations. Robotic arms manage the bulk of the workflow, ranging from attaching antennas to securing the back covers of devices like the Galaxy S26. Production floor lighting is kept intentionally dim to save energy because the automated machinery does not require illumination to operate.
Despite the high level of automation, certain intricate steps still require human technicians. Connecting delicate camera modules to the main board of the Galaxy S26 is handled manually due to the complexity of the task. Most parts are routed through boxy assembly stations arranged across the manufacturing floor, supervised by workers stationed in an adjacent glass-walled control room.
Precision Testing and Quality Control for Foldable Displays
Before packaging, devices undergo rigorous quality assurance testing, particularly high-end models like the Galaxy Z Fold 8 Ultra. According to plant data, the full inspection process takes approximately 30 minutes per device. Automated systems test wireless capabilities including Wi-Fi, Bluetooth, speaker functionality, and audio output.
Specialized machines measure the exact resolution of both the primary foldable screen and the cover display. Camera testing stations analyze color saturation, check for internal dust contamination introduced during assembly, and evaluate optical zoom functions. Once technical checks conclude, human inspectors perform a final exterior assessment before a robotic arm applies seals, inserts the device into its box, and stacks cartons onto shipping palettes.
