iPhone 5 on iOS 8.4 cellular data switches not turning off
HI I've had my iPhone for awhile and I've ignored the issue that the cellular data switches for certain apps do not stay off. The App Store, notes, photos etc always stay switched on which uses my data. I've tried putting the switch off but when I leave settings and go back in they appear to be on once again. can anyone please help me? This uses too much data when i am away from my wifi
