Apple enthusiasts are eagerly awaiting the release of the iPhone 15 lineup in September, which is expected to bring significant upgrades to the base models, particularly in the camera department. A new report suggests that Apple's camera supplier, Sony, is facing production capacity issues, primarily due to the increased demand for colour filter films for the higher-end camera modules. It is speculated that all iPhone 15 models will feature a 48MP primary camera. There are also rumours of a rounded-edge design and a switch from stainless steel to a more durable titanium frame. Furthermore, the entire iPhone 15 lineup will adopt the USB-C port, replacing Apple's proprietary Lightning port. While the base models will now have features previously exclusive to the Pro versions, the iPhone 15 Pro and Pro Max will likely offer greater performance with the exclusive A17 chip.
