OnePlus continues to dole out information about the OnePlus 5 - "what do you 5ee?", a tantalizing photo asks. It's the OnePlus 3T, obviously, but there's something below it. Unfortunately, just like photos of the Loch Ness monster, it's just too difficult to make out any details. Still, from this angle it seems that the OnePlus 5 is smaller than the 3T. All rumors so far have been for a 5.5" screen (ofQHD resolution), but this lends some credence to the dual-edge screen gossip. Screen size is only half the reasons phones are big - the other half is chunky bezels. Look into the shadows....
