It was just a matter of time.

After the dual rear camera became the norm for smartphone flagships,El secreto de la Veneno (1997) XXX movie it's apparently time for the number of selfie cameras on phones to double as well.

Oppo's next smartphone, the F3 Plus, will have a dual selfie camera. We don't yet have any images of the phone but we have a launch date: March 23.

In terms of spec, we only know that the phone will have a 16-megapixel "main" selfie cam, as well as an 8-megapixel "sub" camera on the front.

In its press release, Oppo repeatedly refers to the phone as "F3 Plus of the F3 series," and we've seen reports that the company might actually launch two phones in March, the F3 and the F3 Plus, both with dual front cameras.

Oppo, which is currently the fourth largest smartphone manufacturer in the world, is betting big on phone camera technology. At this year's Mobile World Congress in Barcelona, the company showcased 5x lossless zoom on a smartphone camera, though it hasn't yet launched a phone that uses that technology.

The F3 Plus will launch in five markets where the brand has been especially successful: India, Indonesia, Myanmar, the Philippines and Vietnam. There's no word on the price or availability in the U.S. or Europe at this time.
