According Sammobile, The Samsung Galaxy Note 6 in addition to being waterproof and dustproof and potentially support new Gear VR technology. It will be the first Note to use Samsung’s USB Type-C port designed for mobile phone products.
In fact, when the Galaxy S7 series was released, there where rumors that the Galaxy S7 would come with a USB Type-C design, but in the end this prediction did not come true.[via]
We can now exclusively confirm that the Galaxy Note 6 will feature a USB Type-C port, reversible connector and all. We don’t know whether it will be USB 3.1 or an older standard; it would be logical for Samsung to go with USB 3.1 since it is truly the one port to rule them all. USB 3.1 supports USB Power Delivery 2.0 for faster device charging and the ability to carry HDMI or Display Port video signals.
Gear VR could be handled via the built-in micro USB connection, so if Note 6 is using USB Type-C this can not be used.
So maybe Galaxy Note 6 users will have to do without Gear VR.
