I have noticed that a clock widget on a lock screen keeps changing in size and placement on its own randomly (or I haven't noticed a pattern yet). So, I set a clock widget to a different size than a default one. And then, at some point during a day it changes on its own to a small size and sticks at the bottom of the screen.
One UI 7.
Happens on both devices: my S24 Ultra and my GF's S24.
Thanks for reporting this. The lock screen clock resizing issue has been noted by other users on One UI 7, including on S24 and S24 Ultra devices. It appears to be a bug, and we recommend sending an error report via the Samsung Members app to help the team investigate: Samsung Members > Get Help > Send Feedback > Error Reports > Lock screen
