Almost from the word go, it has taken to 'cycling' through themes (or background colours), one after another, for no apparent reason. It does this even when the phone is not being touched at all.
It occurs especially when I'm actually using the phone for writing a text message, the background will change from black, to grey, to red every few seconds, which is beginning to get more & more annoying!
Additionally, any wallpaper image that I assign seems to disappear after a short time, leaving just a blank theme once again.
Can anyone suggest a way of sorting this out? Is it something that other people have found as a problem?
