According to OnLeaks insider information, OnePlus is working on mid-range smartphones. Its alleged name is OnePlus 8 Lite.

CAD renders from the author of leaks fully reveal the design of the device.
The front side is different from all the other holes in the center for a separate camera, at the back there is a dual camera in a rectangular block with an additional sensor, probably Time-of-Flight.

The screen diagonal is 6.4 or 6.5 inches, on the USB-connector type C, on the right – the power button and slider for switching sound modes. The volume rocker is located on the left side of the case. The dimensions of the device are 159.2 × 74 × 8.6 mm.
The absence of a fingerprint scanner on the case indicates the use of an OLED matrix in the display. There are no other details about the OnePlus 8 Lite. Prior to this, OnePlus released only one mid-budget smartphone – OnePlus X in 2015.
