Roam: turning itself on

Hey all

I got the Roam delivered on Monday, and have experienced some unusual behaviour, which I’ve summarised below:

Powered the Roam off (holding down the power button until the chime), put it on charge (wirelessly) and the Roam immediately turns back on.

So, I powered it down while it was sitting on the charger, which seemed to do the trick, and left it to charge. When I went back to check it a few hours later, it was switched on again!

So I guess my question is this… does the Roam turn on automatically when being charged wirelessly? If so is there a way to turn this feature off?

Thanks
