Oppo has released the A3 Pro, a new mid-range handset that combines a 120 Hz AMOLED display with a large battery and a 64 MP primary camera. The Oppo A3 Pro may look like many other modern smartphones, but it is also one of the few that is IP69 certified, which Oppo complements with Corning Gorilla Glass Victus 2 and Crystal Shield glass.
