Don't Wait for New Screen Sizes
If you're hoping for a drastic change to the iPhone's current array of screen sizes this year year, don't hold your breath.
We could see Apple release a new 4-inch iPhone SE in 2019, but it looks like the company will keep the screen sizes on the other models the same.
According to insider Ming-Chi Kuo, Apple's 2019 iPhones will come with a 5.8-inch OLED display, 6.5-inch OLED display, and a 6.1-inch LCD display. This mirrors the current iPhone XS/iPhone XS Max/iPhone XR lineup. Kuo doubles down on this claim in a new report.
A report from The Wall Street Journal claims Apple will release three models that fall in line with last year's models.
The WSJ also says Apple will drop the LCD display in 2020 moving to a full OLED-powered lineup. A report from May, 2018 claimed the shift to OLED would begin in 2019, but it looks like that's won't happen.
A strange report from Japanese site Mac Otakara claims that Apple is developing two additional OLED devices that will launch alongside the successors for the iPhone XR, iPhone XS, and iPhone XS Max. These devices will reportedly have 6.1-inch and 6.5-inch displays.
There are also iPhone SE 2 rumors swirling, but none of them have come from reliable sources so we don't expect a release in 2019 at this time.
Plans can change over the course of the year, but the WSJ and Kuo are typically pretty accurate with early Apple info so there's a very good chance the company sticks with these sizes for another year.
2020 iPhone rumors suggest the devices will have smaller, and larger, displays.
