Huawei p10 lite how can you turn off the phone that the background and the lock display is constantly changing?

I would like to have my own pictures on the huawei p10 lite as background and lock screen as it makes me really upset that it keeps changing so i don't want to download any apps extra for change so maybe there's a solution on how to get the wallpapers and Can keep the lock screen forever from the gallarie thanks!

Yes there's.

Gallery and pick a picture. Click on the picture and then on the bottom right more. Then click Set As Background (Gallery) in the upper right corner to click the hack and select start or lock screen.

To set up a slideshow with your own images you can search in the settings for background. There you will find another background button. Here you can also select a normal background or turn off the background of the home screen at random.

Now you have 2 more buttons.

Change interval and image source. The first says already what it is and the second you can now select a folder from your galierie to use this as a bottom (the pictures in the folder).
