Red Smartphone Back View

A close-up of the rear side of a red smartphone, showcasing its design elements. You can see the dual camera system and a flash unit positioned in the upper left corner. Below that, a subtle, circular indentation marks the location of a fingerprint sensor. The 'oppo' logo is prominently displayed towards the bottom of the upper half of the phone's back, which appears to have a smooth, appealing finish.
