After I already had problems with the lockscreen on my old HTC 7 Trophy with the 7.8 update, I finally switched over to a Lumia 920. Now I am facing a different problem with the bing-image-of-the-day-lockscreen: It does update, but it does this a few minutes before midnight... So I allways see the image of yesterday on my lockscreen, while I see the actual present image, when I hit the search-softkey.
I've already tried to switch off the lockscreen for a few days and switched it on in the morning, but this did not affect the behavior at all. I've also checked the list of background tasks, but I could not see any task for 'lockscreen', 'bing', and so on.
Is there any way to set the time my phone updates the lockscreen image?
