Wallpaper keeps changing randomly

[Mrinternational]

Hi all, 

 I woke up this morning to see my wallpaper and lockscreen were a picture of weird shapes with numbers in them. I saw I needed a phone update so I did that and changed photo back to what I had but it then changed to another random pic half hour later.

I was told to soft reset which I did and once again changed to my photo. An hour later it again changed to something really random, would someone please help. I'm cautious with everything , haven't done anything strange and have a very good virus protection .

Thank you

 This was the last one it changed to. I don't even have these pics in my phone...

Hi @Mrinternational, do you have 'Wallpaper services' enabled on your phone? You can check this by heading to Settings > Wallpaper and style > Browse my wallpapers > Wallpaper services > Set this to 'None' to disable it.

Mine is set to NONE and it changes every night while i sleep and has since the last update.

@LinRGreenwood: Are the wallpapers that appear taken from the Gallery, or are they random? If they are Gallery images, please try heading to Settings > Wallpaper and style > Change wallpapers > Gallery, and check the 'Selected items' section at the top to see if multiple images have been selected. If they have, tap on the thumbnail of any images you'd like to exclude, leaving your preferred choices in place. Alternatively, if the 'Selected items' section is blank, choose a photo to create a wallpaper, and check to see if this resolves your issue.

Random, pics i have never seen before or have not taken. these are a different picture each morning and it is a  picture of a desert or ocean view or something else. I happens at night when my phone is on the charger while i sleep.

Any idea why it changes every night to a new home screen and lock screen.  I have done all the things you suggested and none of them work.

In my case I noticed it will do so at times but for me it happens because for example il set a video wallpaper thru a 3rd party app (zedge)(awesome selection not just wallpaper) but the previous one will be selected directly through the phones wallpaper manager. And for some reason it will decide to stop the zedge video wallpaper and go back to either default or the one i selected just not thru zedge

This worked for me on Galaxy s22 Ultra+
Selected Settings

Selected Wallpaper and style

Selected Change wallpapers

Scrolled down to bottom - Wallpaper Service and selected Dynamic Lock screen icon

Scrolled down to the very bottom and turned off Auto update.

BTW I know about dynamic wallpaper and it is NOT turned on
