iPhone 11 leaks are already happening, many coming from 3rd party case manufactures, which are pretty legit
Rumors suggest the next-generation iPhones will feature triple-lens rear cameras (with wide-angle, super wide-angle, and telephoto lenses).
the three lenses will be arranged in triangle configuration, necessitating a large, square-shaped rear camera bump. All three iPhones are expected to use this square camera bump design. A triple-lens camera setup has the potential to include benefits like better 3D sensing for augmented reality purposes, 3x optical zoom capabilities, up from 2x optical zoom in the 2018 iPhones, and better performance in low light.
We may also see a revamped front-facing TrueDepth camera system that uses new components, but there will be on design changes to the notch and it appears it will remain the same size as the notch on the 2018 iPhones. All three of the front-facing cameras in the 2019 iPhones are expected to be 12 megapixels, up from 7 megapixels in the 2018 models.
