We can end the speculation: the OnePlus 5 is official, and here are all of the details.
Note: This story is being constantly updated with new information.
Just as expected, the OnePlus 5 has dual cameras on the back — one "main" camera, and a secondary camera with a longer lens and higher resolution. OnePlus is using the tagline "Dual cameras. Clearer photos." throughout its marketing campaign. Now we know that there's a 16MP main camera supported by a 20MP longer-focal-length camera.
We already knew going into the event that the OnePlus 5 has a Snapdragon 835 processor, but now we're also learning about additional specs. There's a familiar 5.5-inch display on the front, using a "standard" 16:9 aspect ratio. Inside there's 6GB of RAM and 64GB of storage.
