Wallpaper issue

[Amerififer]

Hoping someone has a suggestion. Recently my Xperia S had started changing the wallpaper all by itself. I find that I am having to reset the wallpaper to the one I want. Sometimes it just goes to a black backround screen,sometimes one of the default xperia wallpapers.. 

Any ideas whats causing this and how to sort it? Happening almost daily now.. 

Thanks in Advance.

Do you have a taskiller? antivirus? battery apps?

Hiya,

Yes to antivirus and also to battery app. However they have been installed for a very long time and this issue is fairly recent.

uninstall them or restart your phone on safe mode and check again or just repair your phone with SUS or PCC

if that doesn't work, repair your phone with

PC Companion (PCC)
