photo album uses a lot of gigabytes
hi, when I manage my storage in setting I see that my photo album uses 8.4 gigabytes! I tried deleting all of my photos to see if it would make a difference but it didn't. I've also deleted all the photos off recently deleted. The only other apps I have is Facebook and YouTube and of course the other pre installed applications That only take up a certain amount of megabytes. I have zero photos or videos in my photo library so why does it still say 8.4 gigabytes used? And how can I fix this?
iPhone 5, iOS 8.4.1
