  2. Display: 5.5-inch Full HD Optic AMOLED with a resolution of 1080 x 1920 pixels.
  3. Processor: Qualcomm Snapdragon 820 Quad-core.
  4. Memory: 6 GB RAM with 64 GB internal storage (non-expandable).

  1. Performance: With the Snapdragon 820 and a whopping 6 GB of RAM, the OnePlus 3 was a performance beast, handling everything from daily tasks to intensive gaming with ease.
