When the iPhone 14 Pro and iPhone 14 Pro Max schematics were allegedly leaked, both flagships were shown to sport larger rear camera bumps. One analyst believes that is due to the 48MP sensor upgrade that is expected to arrive for both models.

Compared to the 12MP primary rear cameras present on the iPhone 13 Pro and iPhone 13 Pro Max, the iPhone 14 Pro and iPhone 14 Pro Max will likely feature 48MP upgrades. TF International Securities analyst Ming-Chi Kuo previously predicted this camera upgrade, but it is the first time he is providing a reason for a change in dimensions.
