It's worth mentioning that a quad camera setup for the Galaxy S11+ makes more sense. While leaked 360-degree renders of the S11+ had shown what looked like five rear cameras arranged in an X pattern, there have been no reports, leaks, or rumors telling us what the fifth camera will do. It's possible the renders had simply mistaken the two sensors that make up a single ToF camera to be two actual cameras.
ToF cameras have a transmitter module and a receiver module, which is why the Galaxy S10 5G has three holes in the front despite having just dual front cameras – a regular selfie camera and a ToF camera. The Galaxy Note 10+ has five camera sensors at the back as well, with two of them belonging to the ToF camera, and it's likely the Galaxy S11+ (and the regular Galaxy S11) will have the same number of cameras.
While the number of cameras might not change, the Galaxy S11 will bring a substantial upgrade in the camera specs. The primary rear camera is expected to be a 108MP lens and the telephoto camera is expected to be capable of 5x zoom. The former is said to be a special sensor Samsung is designing exclusively for the Galaxy S11 series, and that sensor will also be seen on the Galaxy Fold 2 alongside the 5x telephoto camera.
