storage problem iOS 10.3.1
Hello
The "Other" section of my iPhone 6S 16gb has exploded beyond control, and I have fixed it with every trick possible, including 3 full resets and restores. All 3 times the storage goes back to 4-4.5 GB of memory free, then within an hour comes back to zero KB available. I have even tried to delete all 1300 of my photos, so now they're gone, and have cleared the cache to everything and it still doesn't work. I don't have warrenty for it so I'd love it if someone could help me with this. No matter what I delete the "Other" section will occupy that remaining space.
iPhone 6s, iOS 10.3.1, 16GB
