Smartphone vendors often enter business deals to pre-install popular apps such as Facebook. Apps including Twitter and Booking.com also come pre-installed on Huawei phones in many markets. Twitter declined to comment and Booking Holdings did not respond to a request.
The move by Facebook looks to hit the sales outlook for Huawei whose smartphone business became its biggest revenue generator last year, powered by strong growth in Europe and Asia despite a slump in phone sales demands globally.
Huawei has not offered any comments.
