According to 91Mobiles, Oppo is trying to patent a removable camera module for smartphones. If you wanted to take a selfie or take more over a shot, you’d just have to pull the module from the back and point it at your subject.

The OPPO patent shows that the removable camera module will have a built-in battery as well as connectivity options like NFC, Wi-Fi, Bluetooth, and USB Type-C.
