My iPhone 5c shows wrong time
I have a iphone 5c using it more than 2 years.
One day the lcd crashed, so I bought a new one and replaced it by myself.
It had been off for a month until I received the new lcd.
After the replacement, I found it showed wrong time.
I tried many things, including restore, complete restore after DFU reset, changing settings of location, wifi, modem...etc with vain.
- When I set "Set Automatically" to off, I could set the time.
But every time I set, after some time, the time ran slow and showed wrong time.
Interestingly, when I set Auto-Lock to Never, then the time runs O.K, until I put the phone into sleep by pressing sleep button.
- When I set "Set Automatically" to on, I found a strange thing.
After 25 seconds it goes to "No Service", and come back to service.
It looks like the modem is restarting.
I do not have much understanding on iOS 10.
Can anyone comment on why this thing happens logically?
Is this a good question?
