TOKYO -- The U.S.-China trade war is testing whether smartphone users are more loyal to their devices or the apps that run on them, and the answer is not as clear cut as Donald Trump may have hoped.
Washington's ban on the use of Google services by Huawei Technologies means the Chinese smartphone maker has had to roll out its latest Mate 30 series of smartphones without apps like Gmail and Google Maps. It is one of the more visible attempts by the Trump administration to curb Huawei's growing international reach, and Huawei itself originally estimated the ban would cause sales to fall about $30 billion short of its goal.
