Hi there,
I'm experiencing this problem too. My J7 just had a software update and on the lock screen, when no push notifications are present, the clock is this awful vertical clock. The time will read, instead of 9:15, it will say:
09
15
It looks like a date! This is horrible design! It's driving me nuts and I've only been dealing with it for four hours.
The link provided seems dated and does not help with this problem (at least not with this software update). I cannot find any of the features/settings listed on that article to change within my settings.
I've heard adding contact info on the lock screen would help; it does not help.
I've seen suggestions of themes to download, but I do not want to do that. Also, I read that it tends to reset itself anyways to a vertical clock.
I cannot find anything in my settings to adjust the clock on the lock screen.
Boy, I hope someone can find a solution for this. It's absolutely a bass ackwards design.
