The device will join the Galaxy C10 and Galaxy J7 (2017), as well as the most expected Galaxy Note 8, on the list of the devices that will sport this kind of feature. Though, this information has not been confirmed by Samsung yet.
We are not even 100% sure that the Galaxy Note 8 will feature dual-camera setup, but it will most probably have one. Taken as a consideration that the Apple’s iPhone 8 will have dual-camera setup, this move from Samsung better to be happening right now.
The company is surely testing some devices with dual-camera setup, but all that we need is some evidence. We will surely know soon, as the announcement date of the Note 8 comes very closely.
