The news that the OnePlus 7 has three rear cameras is not altogether surprising. The rumor has been floated as early as March, and that the setup would include a 48- 20- and 5-megapixel camera. Triple-rear cameras are also appearing on more phones, including the Galaxy S10, the Huawei P30 and the upcoming LG V50 ThinQ.

OnePlus did not immediately reply to a request for comment.
