Apple will reportedly upgrade the main camera of the iPhone 14 Pro and iPhone 14 Pro Max to 48MP this year, up from 12MP. The only drawback to this change is that the rear bump is said to be notably visible compared to previous-generation models. Additional leaked specifications reveal why the company will be forced to make these changes.

A boatload of specifications have been mentioned by Weibo user Fishing 8, claiming that the 48MP sensor on both the iPhone 14 Pro and iPhone 14 Pro Max will have a 1/1.3-inch sensor size. With the calculation done by MacRumors, that equals to a 21 percent bigger sensor area compared to the 1/1.65-inch part present in the iPhone 13 Pro and iPhone 13 Pro Max.
