I had the exact same issue. Fixed it from settings,lock screen, always on display, clock style.
Hope the answer helps. I had to dig deeper as I had a lot of info transferred from the old phone.
That is odd! Can you try the device in Safe Mode to see if a third party app may be causing the issue? Please follow these steps to put your device into Safe mode: Turn off your device > Power on your device normally > As soon as you see the Samsung logo, hold the volume down key > Keep hold of the volume down key until you’re onto the home screen > Safe mode will be indicated in the bottom left corner in a small black bar.
