O2 XDA mini S Slider switch problem

[Mannish Boy]

I've just got an O2 XDA mini S, which is great now the O2 Active thing has been disabled, but the slider switch/volume control on the side (top left) of the unit is misbehaving.

When I switch the unit on, the volume control appears and shoots to the top as if I'm holding the slider switch up, although the 'up' part of the switch doesn't even seem to do anything the rest of the time. It's pretty irritating, although it doesn't affect the unit the rest of the time.

Does this sound like a software bug, or a faulty switch?

Any advice would be appreciated before I return the unit to O2.

Thanks in advance.

Unless something is jammed in it, it sounds like the switch is stuck to me. I'd take it back.
