Apple released the biggest redesign to the iPhone in years in 2017. The iPhone X loses the home button in favor of a facial-recognition scanner and a nearly edge-to-edge screen.
In 2018, Apple will bring that iPhone X design to other iPhone models, according to KGI Securities analyst Ming-Chi Kuo.
In a November 2017 note, he predicted that Apple will launch three new iPhone models this year.
One of the phones could feature an edge-to-edge LCD screen and TrueDepth facial recognition that costs between $649 and $749.
Kuo also said he believes Apple is working on a 6.5-inch iPhone with a design like the iPhone X but with a bigger OLED screen.
And Apple will likely give the iPhone X some improvements as well.
We don't know when these new phones will launch, but for the past five years, Apple has announced new iPhones in September.
