We are going to be talking of the OnePlus Open for the next few days, as it does seem to be THE foldable of the year so far. We are going to begin with what we think is its most outstanding feature - nope, not the cameras (sorry, Hasselblad), but the external or 'cover' display. It is hands down the best we have seen on a foldable launched in India, and when you consider that the others have come from Samsung, that's saying something!
