OnePlus is having a launch event on May 14th for the OnePlus 7 and 7 Pro. Today they have tweeted a promo video saying “Bells and whistles make noise” probably indicating Apple and Samsung’s message tone. Followed by “We make phones” which sounds eccentric. In the teaser, they also showed off a triple camera system and the hashtag #OnePlus7Pro indicating that the triple camera will be available to premium devices like 7 pro which is rumoured to have a 90Hz refresh rate. The camera setup might have a trio of standard + telephoto _ + ultra-wide camera else two from those with a depth sensor.
