The device is engineered with a compact design that has a circular AMOLED touchscreen that can be set to display wallpapers, photos and videos when not being directly used. The screen can spring to life as a selfie camera when taking photos to offer a preview of the snapshot or video. The screen can also be removed from the rear of the smartphone and placed into a hanging keychain case to transform it into an interactive accessory. The OPPO Bubble will offer compatibility with a range of the brand's smartphones with additional ones expected to receive support at a later date. The accessory is priced at 499 yuan (~$75).
