Why is the clock on this iPhone completely stuck?
I have a bizarre problem on an iPhone 5c. It works totally fine, except for one thing. The clock does not run while the phone is asleep. No matter what I do, it always goes back to whatever time it was last set at when it goes to sleep.
The clock advances normally if it is awake, but as soon as I put it back to sleep, it jumps back to the same time. If I set the time manually, it will update, but that just becomes the new time that it jumps back to.
Our maintenance guys use their phones for clocking in and out and such, so this obviously breaks the functionality of that crucial app, among other things.
I have tried a complete DFU restore - same problem. I even opened it up and disconnected the battery for a few minutes. It's exhibited the problem with two different SIM cards in it with LTE on and off.
I'll admit - I'm pretty stumped on this one. Any ideas? Thanks in advance!
