Rumor says that the Galaxy Z Fold 4 has a 108MP camera.
Samsung likely used the 108MP sensor from the Galaxy S22 Ultra in the Galaxy Z Fold 4.
The Galaxy S22 Ultra use the 108MP 1/1.33-inch ISOCELL HM3 sensor.
Other rumors suggest that the camera architecture on the back of the Galaxy Z Fold 4 will be just like the Galaxy S22 Ultra.
But it does not have a 10-megapixel periscope.
So it is unlikely that the ZFold 4 will have a 12MP ultraviolet camera and a 10MP telephoto camera with 3x zoom.
There are even rumors that this phone is equipped with a 10MP selfie camera.
Just to mention that the Galaxy Z Fold 3 has a 4MP selfie camera.
