Since OnePlus smartphones often take design inspirations from the phones of the sister company OPPO, it was assumed that the upcoming OnePlus 6T will have a triple camera system just like the one seen on the OPPO R17 Pro. However, there seems to be a change in plan as OnePlus has apparently broken away from the tradition of following the same design language.

According to ZGAR-branded cases of the OnePlus 6T that have shown up online, the phone will have a dual-camera setup at the back. The cases that are being sold on AliExpress have quelled rumours that claimed the OnePlus 6T will have a TOF sensor. This corroborates a recently leaked render which also showed a dual-camera setup. Since case makers are informed of a phone’s dimensions in advance, this seems like concrete evidence, but we still can’t be sure.
