UMC declines expedited Samsung order for Galaxy Z Fold8; GF eyed as backup DDI foundry
Following stronger-than-expected demand for its Galaxy Z Fold8, Samsung Electronics submitted an expedited wafer production request to United Microelectronics Corporation (UMC) that was ultimately turned down. As a result, Samsung scaled back its September 2026 component production volume by 10%. Amid persistent capacity tightness at mature process nodes, Samsung is now evaluating GlobalFoundries (GF) as a secondary foundry partner for its OLED smartphone DDIs, with potential adoption set for late 2027 at the earliest.
