OnePlus is once again outsourcing some of its decisions to the fans. The company is conducting a poll on Weibo for the design of the OnePlus 5 retail box. The box will be either in white or red with a "5" on the front. The number could be faded, 3D or the box may come with landscape orientation. One suggestion includes the words "Hello 5" on the front, suggesting that this could be the official slogan of the new flagship. To help your favorite design win, you must log in on Weibo and cast a vote. Vote here (in Chinese)
