I'm having something of this similar I've tryed and restart it but not working. Problem is when I take photos and videos they will go down to left hand corner but when I press donne there to view them it says I have none I've also taken videos and nada, tryed the screen pictures home and power together and nada. So overall i take photos and videos but they are not saving I'm guessing please help!
