The leaked renders of the iPhone 2019 are the courtesy of OnLeaks and CompareRaja. As per the renders, Apple could retain similar front body as the current iPhone models but this time there will be a smaller notch and slightly thinner bezels. The big change in iPhone 2019 will be the triple camera setup that is stacked horizontally at the center.
The leaked image shows three camera sensors with a circle flash around the middle lens and a microphone below it. The volume rocker and silent switch is placed on the left and the power button is located on the right.
Previously, another leaked render showcased a different square rear-camera setup just like Mate 20. Now, the new render with the horizontal arrangement contradicts the earlier one. Anyway, talking about the iPhone 2019 models is still a very early assumption. They might be in production process and nothing is confirmed yet. If both the leaks are 100% legit prototypes, it is possible that both will be retained as two different models. It is also possible that only one of the leaked prototypes will be retained. The triple rear cameras in the top-end iPhone 2019 will also increase the cost and it might be costlier than the iPhone XS Max.
