The moving camera design evolved as people were seeking a true bezel-less smartphone. The smartphone manufacturers are already in R&D to develop an in-display camera, however, that would take a lot of time. Thus smartphone manufacturers have a moving camera setup for a selfie camera. Some manufacturers are smart that they have a "flip camera" setup where the rear camera flips to take selfie shots.
