OnePlus has been refreshing its design at a rapid pace where we saw the OP6 with a notch similar to the iPhone followed by a teardrop notch on the OP 6T. The OnePlus 6T has already been selling like hot cakes for the past few months; however, it's already time to speculate about its successor.
The new leak showcases a new OnePlus smartphone that is presumably the OnePlus 7. A picture surfaced on a Chinese social media website and later of slashleaks which shows the new device alongside the 6T. Both these devices are in pre-release cases that hides its final design and the new device on the left does not have a visible notch. In fact, there's only a hint of the earpiece at the top edge.
The fact that the rumoured OnePlus 7 has a seamless notch-less design, the ultimate question arises regarding the front-facing camera. Since there is no noticeable cutout on the case for the selfie-camera, it can be assumed that the OnePlus 7 may have a sliding camera. The sliding mechanism will also house other sensors that will be behind the display. There's also an alert slider on the right side above the power button which is in the exact same position as the OnePlus 6T. The only noticeable difference here is the colour of the button.
We've seen sliding cameras on a smartphone before i.e. the OPPO Find X which is manufactured by a company owned by BBK Electronics. BBK Electronics also happens to own OnePlus and it wouldn't be far-fetched to assume that a similar design would be incorporated on the OnePlus 7 as well.January 12, 2019
As it goes with leaks, this OnePlus 7 image has not been confirmed and should be taken with a pinch of salt. Based on the leaks above, Ben Geskin put out a 3D render of the smartphone that would give you a better idea about the smartphone.
