We have 4 all experiencing the same issue. Checking around for a fix, the number one suggestion amounts to 'reduce you usage of the device'. Lord it's getting hard to love Apple these days

Who's making that idiotic advice???? I've not seen it anywhere, especially for something easily correct with either a hard reset, or a restore. Why do something so silly when only a small minority of 400 million iOS users are even reporting a problem and those that have solve it by doing one of those two simple things????
