SEOUL (CONVERSEER) – Samsung Electronics is reportedly set to return to Apple’s camera image sensor supply chain after nearly a decade, with plans to build a new production line in Texas, United States, to supply components for Apple’s iPhone 18 series. The move could challenge Sony’s long-standing dominance as Apple’s exclusive image sensor supplier.
Korean outlet The Elec reported on Tuesday that Apple has begun strategically reshaping its supply chain for future iPhone cameras. Samsung’s new facility in Austin, Texas, is expected to begin supplying image sensors in 2027, marking a major shift in Apple’s procurement strategy.
Strategic Supply Chain Diversification
For years, Sony of Japan has been Apple’s sole supplier of image sensors for iPhones. However, recent reports of potential supply delays between 2023 and 2024 prompted Apple to rethink its strategy. By bringing Samsung back into the supply chain, Apple aims to diversify its sources and reduce reliance on a single supplier, ensuring greater stability and mitigating supply risks.
Samsung last supplied camera components for Apple nearly a decade ago. Its re-entry underscores both Apple’s need for redundancy and Samsung’s technological progress in image sensor manufacturing.
Major Investment from Doosan Tesna
To support Samsung’s capacity expansion, South Korean semiconductor testing firm Doosan Tesna announced this week a 171.383 billion won (approximately ¥858 million) investment in new testing systems, to be acquired between 2026 and March 2027. This amount represents about 21.77% of the company’s total assets, marking one of its largest financial commitments to date.

Doosan Tesna’s expansion is closely linked to Samsung’s new image sensor production line in Texas, which is expected to provide critical components for the iPhone 18 series. Industry analysts believe that this collaboration will place greater emphasis on testing and verification, as Apple is expected to demand extremely high product quality and yield rates.
Technological Advancements in Sensor Production
Doosan Tesna, a semiconductor testing subsidiary under Doosan Group, was formed in 2022 after acquiring Tesna. It specialises in back-end semiconductor testing for camera image sensors (CIS), application processors (AP), and RF chips, with over 90% of its revenue tied to Samsung’s foundry and system LSI divisions.
In preparation for the new project, Doosan Tesna has started purchasing advanced testing systems from Japan’s Advantest, moving away from its previous reliance on Teradyne equipment. Advantest’s systems are widely used to validate high-performance chips such as GPUs, memory, and AI processors. This shift suggests that the image sensors destined for Apple will be more complex and powerful, requiring higher verification standards to meet Apple’s performance and reliability expectations.
A New Era in iPhone Camera Supply
The establishment of Samsung’s new facility in the US not only reflects Apple’s broader supply chain diversification but also signals intensifying competition in the image sensor market. If successful, Samsung’s return could reshape the balance of power between major suppliers, potentially pressuring Sony to innovate further.
The iPhone 18 series is expected to launch in 2026, with production for its camera components beginning in advance. While The Elec notes a possible timeline discrepancy with references to 2027, the strategic significance of Samsung’s move remains clear: Apple is laying the groundwork for a more resilient and technologically advanced camera supply chain.
