Iphone 5C clock displays incorrect time
I have an iPhone 5C, which has run smoothly for the past year-and-a-half on the Verizon network. Recently, it has started displaying the wrong time at random and sometimes even displays the wrong date. I have found that this also interferes with the phone's ability to receive iMessages.
The steps I have taken so far to fix it are:
- Powered the phone off and back on again.
- Connected the phone to the computer.
- Updated the iOS to 8.3.
- Gone to Settings > General > Date & Time, and ensured that the "Set Automatically" feature is on, and displaying the correct time zone.
- Ensured that Location Services are set to "on."
- Tried turning the Date & Time "Set Automatically" feature off and manually setting the time, but the phone still loses time after a matter of minutes.
- Taken the phone to the Apple Store, where the representative restored it to factory settings. The problem persists even afterwards.
- Spoken with representatives from Verizon, who assure me the problem is not on their end.
I would be very grateful for any help that could be offered. It is very frustrating to not be able to communicate reliably, and to not have an accurate time-keeping device.
