According to the Android Police report, some Huawei smartphone users noticed that the lock screen on their device suddenly displayed ads. Ads for Booking.com pages are displayed immediately on the lock screen of Huawei smartphones.
It seems that Huawei has included advertising images in the Magazine Unlock feature. This is a feature that automatically changes the wallpaper of the lock screen, every time a user unlocks a smartphone. However, these wallpapers are all user-selected.
Although neither Huawei nor Booking.com has responded yet, a Huawei representative in Germany apologized to users on Twitter. Huawei in Germany apologized to users because the ads were suddenly displayed on their lock screen, and said that users could turn off these ads by going to the settings to delete each photo of Booking. com.
Huawei's display of ads on the lock screen without notice has angered many users. Especially when Huawei is a topic of great interest, after a ban from the US and Google and many technology companies stop cooperating.
It seems to compensate for the losses from the US ban, so Huawei sought to increase revenue from its current user base. In which the display of ads on smartphones is one way, but this is also a double-edged sword because it will make users uncomfortable and can choose other smartphones.
