iOS 8.4 memory problem
since i updated my iphone to ios 8.4 the memory on my phone has been messed up. on my phone it says i have a few megabytes left but when you add up how much memory the apps use it doesn't equal the memory used number. i should have about 4 gigabytes left but my phone thinks i used them or something. when i sync it to itunes it knows i still have memory left but my phone doesn't. i have a 16 gig iphone 5s on ios 8.4
both pictures are from the same phone
iPhone 5s, iOS 8.4, null
