Oppo has just released the A3, a lower mid-range handset that mates a 120 Hz OLED display to the aging Snapdragon 695 chipset and a 5,000 mAh battery. The A3 may look like any other modern phone; it's the rather durable case (in no small part thanks to the Corning Gorilla Glass 7i) including water resistance that helps it stand out from the crowd.
