Huawei: Change the Home Screen and Lock Screen Wallpaper

The wallpaper on a Huawei phone is managed from one central menu, but it controls two separate screens: the lock screen and the home screen. That separation is why a picture set once does not automatically appear everywhere, and why some users think the change did not save.

To update it, open Open the settings ➔ Tap on Home screen & wallpaper ➔ Tap on Wallpaper. From here you can pick a photo from your own gallery or select one of the preinstalled wallpapers that come with the device.

After choosing an image, tap Save. EMUI then asks where the wallpaper should apply: Lock screen, Home screen, or Both. Selecting only one keeps the other screen on its previous image, which is useful if you want a plain lock screen but a personal home screen, or the other way around.

If the wallpaper still looks unchanged afterward, check that you picked the correct target screen in that last step rather than repeating the whole process.
