Recently, a supply chain schematic was leaked by SlashLeaks. The image is from a welding pattern that appears to be the iPhone 11, and while details are scarce, it further reinforces the idea of the camera design. That said, the schematic does seem to line up with an earlier report. That the iPhone 11 will sport a square camera bump housing a triple camera setup. On a side note, The camera housing looks remarkably identical to the Huawei Mate 20 series, but the individual sensors are arranged differently.
Apple has not released any official announcement for the next generation iPhone yet. Until then, we do advise you to treat this new as hearsay and take it with a grain of salt. (Source: Twitter, Techradar // Image: @OnLeaks, SlashLeaks)
