I'm not understanding how I'm constantly running out of storage space on my phone. When I go to my storage settings it says that the thing that's taking up the most space (6.5 gigs) are Messages, and when I click on that it says saved messages. I've deleted all of my text messages and iMessages on my phone, and it still says 6.5 gigs are being taken up by Messages. How do I get rid if these and free up space?
