Fresh rumors regarding 2019's Apple iPhone release have begun to circulate, speculating that the update to last year's models will be bigger and feature three cameras on the rear.

Reports were first published by Japanese Apple blog Macotakara (since followed by The Verge and 9to5Mac). They state that the new iPhones will be direct successors to 2018's iPhone XR, XS, and XS Max. Apparently there will be two new models that boast 6.1-inch and 6.5-inch OLED displays.

What's more, these OLED phones are said to be slightly thicker than their predecessors, but by barely-noticeable fractions of a millimeter.

The verdict is out on what exactly the reverse triple-camera system is for,  but the most likely suggestion is that its all down to offering users a wide range of zoom and a larger field of view. Initial ideas included a depth-sensing 3D camera, but Bloomberg reports that this has be pushed back and will debut on an iPad Pro model set to release next year.
