It can be seen in conjunction with the OnePlus 6T called OnePlus 7, as seen in the leaked image. The focus is clearly on the top half of the two devices and this is the point of the entire leak. The phone on the left side of the OnePlus 7 has a frameless display and no notches. By the way, the phone on the right is the OnePlus 6T, which we all know, with a notched water drop style.
Interestingly, the front-facing camera is not a place to see in OnePlus 7. It is not known where the company will place a selfie camera, but it is clear that OnePlus 7 may be a pop-up camera feature such as a Vivo Nex or a sliding camera design like Mi Mix.
