Samsung S9+ wallpaper vanishes

[pacuk01]

I usually have one of my photos as my wallpaper. Recently every now and again  this pictures vanishes and I end up with a completely black wallpaper. If I reboot the phone the usual photo reappears back as my wallpaper.

Thats weird @pacuk01 

WhTW happens if you choose another wallpaper ?

[pacuk01]

No, I haven't tried that yet. I have however noticed some hours after it has vanished I get a notification saying "Welcome to your new case" which isn't true. I have had the Samsung LED case since i had the phone some 18 months or so.

It's not some power saving setting? I know it can do various things in the background.

Cheers guys! 

@pacuk01 , For that "Welcome to your new case"  notification try Settings > Apps > Galaxy Themes > Notifications > toggle off 'Phone case attached'. That should make that message disappear from then on.

You can always toggle that option back on if you want a sound notification to let you know the case is successfully attached though.

Many thanks for your help peeps. I have changed the settings as suggested for new case. I usually only see it when they do an update but seems to appear more and more recently. But have turned that switch off now. The wallpaper has been good and behaving for a day and a half...so just have to wait and see. I thought it might be a particular app I have been in to causing it but so far so good

No worries, @pacuk01 . Let us know how it goes. 

[pacuk01]

Will do.

I spoke too soon.....poof and my wallpaper has gone to an all black background again. I have tried a different background too and that made no difference.

And now it has come back all on its little lonesome.
