A patent application from Samsung suggests that they have a new camera module in progress for phones that use up to six camera lenses. Not only that, all lenses can also be tilted in different directions. For example, it can be used to take larger panoramic images. In addition, patents indicate that the camera module can also be moved in and out of the phone, which can improve the zoom quality.
If or when we'll see this in a Samsung phone is unclear but it is speculated that it is something that will be in the Galaxy S30, which is expected to be released next year.
