The keyboard on my wife's Xperia X10 Mini has just started producing letters of its own accord! i.e. if you go to type a text message, as soon as you slide out the keyboard it starts 'typing' the letters 'edscx' apparently at random, over and over again, without any of the keys being pressed! Everything works ok if you slide the keyboard shut and use the touch-screeen keyboard, it's just the physical slide-out keyboard that does this.
Has anyone else experienced this?
