A new wave of smartphone camera innovation may be on the horizon, as fresh leaks suggest both Oppo and Honor are testing high-resolution square-format selfie sensors for their upcoming flagship devices.

According to well-known tipster Digital Chat Station, the upcoming Oppo Find X10 series is expected to feature a Samsung-developed 100MP front-facing camera sensor. The sensor is reportedly a 1/2.5-inch unit that uses a 1:1 square format rather than the traditional rectangular design found in most smartphones.

The leak follows earlier reports that Oppo was exploring square selfie camera technology for future flagship models.

In a separate report, the same source claims that the upcoming Honor Magic9 series is also being tested with a 100MP selfie camera. Honor is reportedly evaluating the OVA0B sensor, a larger 1/1.8-inch sensor that would be cropped into a square 1:1 format.

The Magic9 series could also receive substantial upgrades on the rear camera system. Current testing is said to include a 200MP primary camera paired with a 64MP periscope telephoto lens.

Honor is reportedly evaluating multiple 200MP main camera sensors, including the OV52A and OV52B, both measuring 1/1.28 inches, as well as the larger 1/1.12-inch OVB0D sensor.

The shift toward square-format selfie cameras could offer several practical advantages. Unlike traditional sensors, a 1:1 sensor captures a larger image area, allowing users to crop photos into portrait or landscape orientations without rotating the phone during capture.

The wider capture area can also help fit more people, scenery, or background elements into selfies, making the camera more versatile for both individual and group shots.

With multiple manufacturers now reportedly exploring the technology, square-format selfie sensors could become one of the next major trends in flagship smartphone photography over the coming years.
