Huawei launches what could be the world's most powerful and feature-packed 5G smartphone on Thursday, but the fate of the device in Europe will hang on whether it can overcome a U.S. ban to give customers the Google software they expect.

The Chinese telecom giant will showcase its Mate 30 range in Munich, Germany, in its first unveiling of an all-new phone since President Donald Trump hit the Shenzhen-based company with an export ban in May.

"The launch will be the most watched ever," said telecom and media analyst Paolo Pescatore.
