Samsung Galaxy S4 lockscreen clock lag

I have a Samsung Galaxy S4 (GT-i9506), which is a nice phone, and I’m quite content with it. So content that when we needed another smartphone in the house, we bought a second one.

Now, on the second phone, there is a strange bug. When activating the phone from sleep, checking the lockscreen clock, the time displayed has a time lag, that might be a few seconds or minutes, or even hours, and it may take several seconds for it to get and show the current time. Clicking the power button twice, ie. switching the lockscreen off and on again, forces the phone to show the current time.

Searching for this bug on google gives a lot of hits, so I guess this is a quite common problem, but it does not plague all users, only a few. The most common forum answer is either to ignore it, or just to switch to another lockscreen widget. Samsung, in their Divine wisdom, does not allow changing the clock widget on a lock screen, unless the actual lock (pin, pattern, etc) is removed, and that is not an option for us.

For our phones, the problem is only visible on the second phone, not the first one. The phones are running the same firmware (Android 4.4.2 Kitkat), and roughly the same software and configuration. Both get current time from the network. But they have different carriers, roaming on different networks.

So, I have this theory: When activating the phone from sleep, it shows the lockscreen as it was when it went to sleep including the time, while asking the telephone network for the current time. And some networks use more time to serve current time of day to the phone than others.

To work around the problem, simply switch off using network-provided date and time, and trust the built-in clock.

Settings -> More -> Date and time -> Automatic date and time

If my theory is correct, Samsung should change their lock screen widget to show local time from the internal clock while waiting to get updated time from the network, when activating the phone from sleep.
