From a tiny robot which strikes a pose when you point a camera at it to earbuds that translate languages, there's all sorts of eye-catching devices on display at the Mobile World Congress trade fair which opened on Monday in Barcelona.
Phone makers are focusing on foldable screens and the introduction of blazing fast 5G wireless networks at the fair as they try to reverse a decline in sales of smartphones.
Samsung, the world's biggest seller of smartphones, unveiled a handset last week that folds open to be a tablet, while Huawei has now followed suit.
