Apple is preparing a brand new, never-before-used screen size for its first 5G models, the iPhone 12 2020 series. The tentatively called iPhone 12 is expected to land with a 5.4″ display diagonal, and, thanks to using the notch front design, be slightly more compact than the 4.7″ iPhone SE 2020 even.
This would be a brand new form factor for Apple, sitting right smack between the 4.7″ iPhone SE, and the 6.1″ iPhone 12 models, but will offer powerful hardware in a package a tad smaller than the SE.
