According to the AppleInsider the iPhone 12 models with a 5.4-inch screen, one of 6.7 inches, and two of 6.1 inches. The largest model of 6.7 inches, along with one of those 6.1, should offer higher-end specifications than the others. Including the triple photo module on the back and the “World-facing 3D sensing “.
The remaining two models, namely the 5.4 and the 6.1-inch second models. They should have only a dual-camera module, without the “3D sensing”. Moreover, although we expect that all models will support the 5G networks. Only the “Pro” will include support to Mmwave 5G, while others will only be available with sub-6GHz 5G.
According to JP Morgan (AppleInsider), we could see a shift in timing starting 2021. Which would involve the release of two new iPhones in the first half of 2021. Followed by two more new models in the second half.
