Update – see the official response and how to remove from Huawei.
According to Huawei users on Twitter, ads for the hotel reservation site Booking.com are popping up on the lock screen of some Huawei and Honor smartphones. The ads seem to appear on devices using the pre-installed landscape wallpapers. They’ve been spotted in several countries — including the UK, Netherlands, Ireland, South Africa, Norway and Germany — and on various models including the latest P30 Pro.
Both Huawei and Honor representatives deny any knowledge of adding adverts to the lockscreens and are consequently investigating. It seems to point to an app Booking.com which may be the culprit.
