is there anything interfering with the signal because if there is that may be the reason like something solid between the gamepad and the console so is it still doing it now I mean have you tried connecting it again because sometimes these things just happen unless it's the battery because it could be low on power so you will want to make sure that it is fully charged since it uses bluetooth maybe there is some kind of interference nearby but I am not sure how that would happen because I don't own a smartphone but you may want to send it to nintendo for repairs if that doesn't work but I don't know so good luck
