In my experience, this is also the case when buying small cloth, because it is broken and the contact is poor, but I don't know why, sometimes there is electricity to say a few words, and even inexplicable words. But sometimes you press him and there is no response. It should be the problem of circuit connection. Now I bought a rabbit, story machine, which has a solid workmanship and a silicone cover, and is more resistant to falling. It works normally.
