This is the resource SamMobile. They once predicted a USB Type-C for smartphones Galaxy S7 and S7 Edge, which really did not happen. I assume that Samsung did not rush to update the USB because its Gear VR would be unable to work with devices directly, without any adapters or other similar devices. But the company plans such as the upgrade and Gear VR, and therefore all the appearance of the USB Type-C u Note 6 it seems very likely.
About the anticipated phablet Samsung Galaxy Note 6, we already wrote a bit earlier. Here and here. Now the network is rife with the news that this smartphone will receive the long-awaited USB Type-C.
