Apple Inc. (AAPL  ) could encounter delays in producing the iPhone 15 and iPhone 15 Plus because of a stacked 48MP camera sensor.

What Happened: Jeff Pu, a tech analyst at Hong Kong-based investment firm Haitong International Securities, reaffirmed an earlier statement made in January that the iPhone 15 and iPhone 15 Plus are expected to incorporate a rear camera with a three-stacked sensor.

According to Pu, the camera would be a 48-megapixel lens, capturing more light and enhancing the picture quality.

However, after the recent supply chain inspections, he speculated that the stacked sensor might encounter yield problems that could delay the production of these devices, reported MacRumors, citing the research note.

It is believed that the upcoming iPhone models are on track for their September release, but Pu said he would watch for any potential hazards that may affect the production timelines.

In the same note, Pu further highlighted the adoption of USB-C port across all models, the retention of the same capacities as the iPhone 14 generation and the utilization of the A16 chip in non-Pro models while the Pro devices will transition to the A17 chip, the report noted.

Why It's Important: Last year, Apple debuted a 48-megapixel camera lens on the iPhone 14 Pro and iPhone 14 Pro Max. This lens permits users to capture 48-megapixel ProRAW photographs that preserve a higher level of detail within the image file, providing greater flexibility during editing.
