Lock screen and Home screen wallpaper

[Arun36]

Hi,

Am using Samsung Galaxy S10 Lite.  Initially i didn't have this problem but now i started facing it.  Whenever i tried to change the Lock screen and Home screen wallpaper, it gets changed but after few seconds again it restores the default wallpaper for both Lock screen and Home screen.  Need help how get out of this problem.
