Updating default wall paper

[ANDREWLOFGREN]

Hello,

I am looking to update our default wallpaper settings for iOS. We currently have a lock screen image and home screen image. I am wondering if I update these files will they only install on devices enrolled after the change? I just want to make sure that its not going to update every MDM phone with the new wallpaper as most users have custom ones once they get their phone and personalize it.

When default wallpapers (home screen/lock screen) are changed, these changes are updated immediately on all iOS-devices.

That's why users like the MDM admin.
