Here is a picture of the OnePlus 5 and OnePlus 5T stacked together
To make things even more obvious, OnePlus posted a picture of its current and upcoming flagships stacked together. What you see in the picture is the rear side of the OnePlus 5, which hides the entire silhouette of the OnePlus 5T.
The only thing we can tell is the OnePlus 5T will be slightly bigger than the OnePlus 5, probably due to the larger 6-inch display that could be included. Also, once again, OnePlus confirms the name of the forthcoming device: “5Tacked. #OnePlus5 #OnePlus5T.”
Although we don't have official word yet, the OnePlus 5T is expected to be unveiled in mid-November. The smartphone should go on sale not long after that, though OnePlus might be forced to adopt a phased roll-out in order to be able to meet customer demand.
