Design and Build
The Oppo R819 is designed with simplicity and functionality in mind. It measures 136.5 x 68 x 7.3 mm and weighs just 110 g, making it quite compact and lightweight, even by modern standards. This slim profile allows the phone to comfortably fit in hand. The device supports dual SIM slots with dual stand-by capability, accommodating micro-SIMs, which was a popular format during the device's release.
