Iphone 6 email reverts to 1970 I have an iPhone 6 on iOS 8.4.

My problem is that the emails keep getting set back to 1970 and are blank. This happens every single day and I have to wait hours for it too fully sync again.

the resolution was to turn off the background app refresh in settings then general
