@Kitkat11xx, and read them, you will find out that the rattling you are hearing is almost certainly the optical image stabilization system on your device letting you know it is there when you are shaking your device. This is a common issue that concerns a lot of people when they first detect it. ESPECIALLY if they first hear it after dropping the device and being worried about any potential damage caused. Your S23 is built like a tank internally please believe me, and any noteworthy internal damage would make itself known immediately. If your camera is still working fine through all it's lenses, then you almost certainly have nothing to worry about. If this is the case, I hope you can enjoy your device again and really get some great use and satisfaction from it.
