A21S Home screen wallpaper is not staying for longer than a minute.

I'm using Samsung Galaxy A21S. From last couple of days , my home screen wallpaper is not working properly. It is staying for few seconds and getting vanished automatically and showing a black home screen after that. 

Anyone has faced similar issue or can help on how to fix the issue. Thanks

You can try these steps

A. Reset App Preferences.
Settings >Apps> Tap on Top Right 3Dots and select Reset App preferences.

B. Go to settings >general Management >reset>reset settings.

(NOTE : Reset settings/ Reset App preferences, change all settings to default)
