Oppo patent application reveals phone with a foldable top
With the selfie camera on the top half of the device, it would be possible for one camera to be both the rear-facing and front-facing snapper by bending backward and forward. If this patent application ends up forecasting a new Oppo phone design, it wouldn't be the first time that the manufacturer released a handset that employed one camera as the rear shooter and the front-facing selfie snapper. In 2013, Oppo released the N1, a phone that was equipped with a rotating top. This allowed the 13MP camera to spin 206 degrees so that it could be used on the back and front of the phone.
Just because Oppo has filed this patent application, it doesn't mean that we can count on such a model to be released. Many ideas that receive a patent never make it to the marketplace. However, with Oppo's background in making cameras that can work from both sides of a phone, this seems to be right in the company's wheelhouse.
