Please help me. I have deleted apps and photos to get memory on my iPad, and it still says I have 0gb left. It has been a couple of weeks. All photos have been deleted from the 'recently deleted' album. It says the camera roll is using 7.5gb, when there are no photos. It's affecting my iPad speed. I've tried rebooting my iPad. I can't install anything, as my memory is used up. It has 16gb, and I think it's an iPad 2.
Note: I don't have a Macpro, MacBook, iPhone, iPod, iMac or anything else made by Apple.
