New renders of the OnePlus 9 Pro indicate that the smartphone will feature a mix of the OnePlus 8 Pro and OnePlus 8T designs with a punch-hole selfie camera at the top-left corner and a curved display. The rear camera mount is now towards the top-left and is likely to include four lenses. The OnePlus 9 Pro is likely to be unveiled as early as March next year.
