According to a survey on China's Twitter-like social media platform Weibo, about 95 percent of 1.2 million people that responded said they would switch to an Android smartphone over an iPhone rather than give up WeChat if it were banned.
It was unclear how the administration could implement the ban on WeChat in mid-September. It could order Apple Inc and Alphabet Inc's Google to remove WeChat from their app store, or order the apps to stop offering access or updates to U.S. users.
Bryant also cautioned against a disruption in cross-border investment, as her company helps bring in investment from around the world, especially China.
Some Chinese immigrants and expats worry losing access to the popular WeChat could cut off contact with family and friends in China.
In the U.S., WeChat app downloads in the U.S. rose by 41 percent in a six-day average from the week prior to the U.S. ban announced last Thursday, and QQ downloads have tripled in the past week, according to data from Sensor Tower.
