My new i1236 Polaroid digital camera will turn
1) The card could be write protected, check the side of the card see if there's a small notch to slide up or down.
2) The camera could have photo protection option switched on, you have to go through the user manual and the camera menu to switch that off.
3) If you don't get too far with the first options, as its new, take it back to the vendor and ask them to demonstrate it to you and to your satisfaction. If there is a problem with the camera, request a replacement or refund under warranty.
