According to a brand new report from South Korea, Samsung's upcoming Galaxy S10 smartphone could feature a triple rear camera. Korean website The Information quotes a local analyst who says that Samsung is "considering" equipping the Galaxy S10 with such a camera possibly because Apple is expected to launch an iPhone X Plus with a triple camera sometime in 2019.
The new report also reiterates a rumor about a 3D sensing sensor that could be included in the camera of the Galaxy S10 - this would allow the recording of high-definition 3D content, from selfies to stuff that can be used in AR (Augmented Reality). This 3D sensor does not necessarily require a triple camera. Still, having a triple rear camera should bring various other benefits, including enhanced optical zoom, increased image sharpness, and superior low-light performance.
At this moment, the specifications of the triple camera that Samsung might use on its Galaxy S10 are not known. Anyhow, Huawei already released a smartphone featuring a triple camera on the back - the P20 Pro, which, as you'd expect, takes really good photos. The triple shooter of the Huawei P20 Pro (pictured above) includes a 40 MP main camera for regular shots, a 20 MP monochrome camera, and an 8 MP telephoto (zoom) camera. Samsung may go for a relatively similar setup, but that's just a faint guess.
A recent rumor had it that the Samsung Galaxy S10 series (likely including 5.8-inch and 6.3-inch models) could be announced in January 2019, less than a year after the Galaxy S9. We'll just have to wait and see if that's true.
